O'Mega, O'Caml 3.01: incompatible changes
O'Mega, src/trie.mli: add covariance annotation to T.t
This breaks O'Caml 3.00, but is required for O'Caml 3.01.
O'Mega, many instances: replace `sig include Module.T end' by
`Module.T', since the bug is fixed in O'Caml 3.01
2001-02-28
O'Mega, src/model.mli:
new field Model.vertices required for model functors, will
retire Model.fuse2, Model.fuse3, Model.fusen soon.

\chapter{Generic Event Handling}
\includemodulegraph{events}
Event records allow the MC to communicate with the outside world. The
event record should exhibit the observable contents of a physical
event. We should be able to read and write events. The actual
implementation of the event need not be defined yet, for that purpose.
We have the following basic modules:
\begin{description}
\item[event\_base]
Abstract base type for event records. The base type contains a
reference to a [[particle_set_t]] object as the event core, and it
holds some data that we should always expect, such as the squared
matrix element and event weight.
\item[eio\_data]
Transparent container for the metadata of an event sample.
\item[eio\_base]
Abstract base type for event-record input and output. The
implementations of this base type represent specific event I/O
formats.
\end{description}
These are the implementation modules:
\begin{description}
\item[eio\_checkpoints]
Auxiliary output format. The only purpose is to provide screen
diagnostics during event output.
\item[eio\_callback]
Auxiliary output format. The only purpose is to execute a callback
procedure, so we have a hook for external access during event output.
\item[eio\_weights]
Print some event summary data, no details. The main use if for
testing purposes.
\item[eio\_dump]
Dump the contents of WHIZARD's [[particle_set]] internal record,
using the [[write]] method of that record as-is. The main use if for
testing purposes.
\item[hep\_common]
Implements traditional HEP common blocks that are (still) used by
some of the event I/O formats below.
\item[hepmc\_interface]
Access particle objects of the HepMC package. Functional only if this
package is linked. The interface is working both for HepMC2 and HepMC3.
\item[lcio\_interface]
Access objects of the LCIO package. Functional only if this
package is linked.
\item[hep\_events]
Interface between the event record and the common blocks.
\item[eio\_ascii]
Collection of event output formats that write ASCII files.
\item[eio\_lhef]
LHEF for input and output.
\item[eio\_stdhep]
Support for the StdHEP format (binary, machine-independent).
\item[eio\_hepmc]
Support for the HepMC format (C++).
\item[eio\_lcio]
Support for the LCIO format (C++).
\end{description}

\section{Generic Event Handling}
We introduce events first in form of an abstract type, together with
some utilities. Abstract events can be used by other modules, in
particular event I/O, without introducing an explicit dependency on
the event implementation.

@
\subsection{Initialization}
This determines the number of alternate weights and sqme values.
<<Event base: generic event: TBP>>=
procedure :: base_init => generic_event_init
<<Event base: procedures>>=
subroutine generic_event_init (event, n_alt)
class(generic_event_t), intent(out) :: event

event%n_alt = n_alt
allocate (event%sqme_alt (n_alt))
allocate (event%weight_alt (n_alt))
end subroutine generic_event_init
@ %def generic_event_init
@
\subsection{Access particle set}
The particle set is the core of the event. We allow access to it via
a pointer, and we maintain the information whether the particle set
is valid, i.e., has been filled with meaningful data.
<<Event base: generic event: TBP>>=
procedure :: has_valid_particle_set => generic_event_has_valid_particle_set
procedure :: accept_particle_set => generic_event_accept_particle_set
procedure :: discard_particle_set => generic_event_discard_particle_set
<<Event base: procedures>>=
function generic_event_has_valid_particle_set (event) result (flag)
class(generic_event_t), intent(in) :: event
logical :: flag
flag = event%particle_set_is_valid
end function generic_event_has_valid_particle_set
subroutine generic_event_accept_particle_set (event)
class(generic_event_t), intent(inout) :: event
event%particle_set_is_valid = .true.
end subroutine generic_event_accept_particle_set
subroutine generic_event_discard_particle_set (event)
class(generic_event_t), intent(inout) :: event
event%particle_set_is_valid = .false.
end subroutine generic_event_discard_particle_set
@ %def generic_event_has_valid_particle_set
@ %def generic_event_accept_particle_set
@ %def generic_event_discard_particle_set
@
These procedures deal with the particle set directly. Return the pointer:
<<Event base: generic event: TBP>>=
procedure :: get_particle_set_ptr => generic_event_get_particle_set_ptr
<<Event base: procedures>>=
function generic_event_get_particle_set_ptr (event) result (ptr)
class(generic_event_t), intent(in) :: event
type(particle_set_t), pointer :: ptr
ptr => event%particle_set
end function generic_event_get_particle_set_ptr
@ %def generic_event_get_particle_set_ptr
@
Let it point to some existing particle set:
<<Event base: generic event: TBP>>=
procedure :: link_particle_set => generic_event_link_particle_set
<<Event base: procedures>>=
subroutine generic_event_link_particle_set (event, particle_set)
class(generic_event_t), intent(inout) :: event
type(particle_set_t), intent(in), target :: particle_set
event%particle_set => particle_set
call event%accept_particle_set ()
end subroutine generic_event_link_particle_set
@ %def generic_event_link_particle_set
@
\subsection{Access sqme and weight}
There are several incarnations: the current value, a reference value,
alternate values.
<<Event base: generic event: TBP>>=
procedure :: sqme_prc_is_known => generic_event_sqme_prc_is_known
procedure :: sqme_ref_is_known => generic_event_sqme_ref_is_known

procedure :: weight_prc_is_known => generic_event_weight_prc_is_known
procedure :: weight_ref_is_known => generic_event_weight_ref_is_known
procedure :: weight_alt_is_known => generic_event_weight_alt_is_known
procedure :: excess_prc_is_known => generic_event_excess_prc_is_known
<<Event base: procedures>>=

\subsection{Callback container}
This derived type contains a callback procedure that can
be executed during event I/O. The callback procedure is given the
event object (with class [[generic_event]]) and an event index.
This is a simple wrapper. The object is abstract, so the the actual
procedure is introduced by overriding the deferred one. We use the
PASS attribute, so we may supplement runtime data in the callback object
if desired.

\subsection{Event Sample Data}
These are data that apply to an event sample as a whole. They are
given in an easily portable form (no fancy structure) and are used for
initializing event formats.
There are two MD5 sums here. [[md5sum_proc]] depends only on the
definition of the contributing processes. A sample with matching
checksum can be rescanned with modified model parameters, beam
structure etc, to recalculate observables. [[md5sum_config]] includes
all relevant data. Rescanning a sample with matching checksum will
produce identical observables. (A third checksum might be added which
depends on the event sample itself. This is not needed, so far.)
If alternate weights are part of the event sample ([[n_alt]] nonzero),
there is a configuration MD5 sum for each of them.

\section{Abstract I/O Handler}
This module defines an abstract object for event I/O and the
associated methods.
There are [[output]] and [[input]] methods which
write or read a single event from/to the I/O stream, respectively.
The I/O stream itself may be a file, a common block, or an externally
linked structure, depending on the concrete implementation.
A [[write]] method prints the current content of the
implementation-dependent event record in human-readable form.
The [[init_in]]/[[init_out]] and [[final]] prepare
and finalize the I/O stream, respectively. There is also a
[[switch_inout]] method which turns an input stream into an output
stream where events can be appended.
Optionally, output files can be split in chunks of well-defined size. The
[[split_out]] method takes care of this.

\section{HEP Common Blocks}
Long ago, to transfer data between programs one had to set up a common
block and link both programs as libraries to the main executable. The
HEP community standardizes several of those common blocks.
The modern way of data exchange uses data files with standard
formats. However, the LHEF standard data format derives from a common
block (actually, two).
\whizard\ used to support those common blocks, and LHEF was
implemented via writing/reading blocks. We still keep this
convention, but intend to eliminate common blocks (or any other static
storage) from the workflow in the future. This will gain flexibility
towards concurrent running of program images.
We encapsulate everything here in a module. The module holds the
variables which are part of the common block. To access the common
block variables, we just have to [[use]] this module. (They are
nevertheless in the common block, since external software may access
it in this way.)
Note: This code is taken essentially unchanged from \whizard\ 2.1 and
does not (yet) provide unit tests.

negative weights are allowed (and are reweighted to $\pm 1$ by the

The HEPRUP (event) common block is needed for the interface to the shower.
Filling of it is triggered by some output file formats. If these are not
present, the common block is filled with some dummy information. Be generous
with the number of processes in HEPRUP so that PYTHIA only rarely needs to be
reinitialized in case events with higher process ids are generated.

If the particle has a full polarization density matrix given, we need
the particle momentum and polarization as well as the mother-particle
momentum. The polarization is transformed into a spin vector (which
is sensible only for spin-1/2 or massless particles), which then is
transformed into the lab frame (by a rotation of the 3-axis to the
particle momentum axis). Finally, we compute the scalar product of
this vector with the mother-particle three-momentum.
This puts severe restrictions on the applicability of this definition,
and Lorentz invariance is lost. Unfortunately, the Les Houches Accord
requires this computation.

\subsection{The HEPEVT and HEPEV4 common block}
For the LEP Monte Carlos, a standard common block has been proposed
in AKV89. We strongly recommend its use. (The description is an
abbreviated transcription of AKV89, Vol. 3, pp. 327-330).
[[NMXHEP]] is the maximum number of entries:
<<HEP common: variables>>=
integer, parameter :: NMXHEP = 4000
@ %def NMXHEP
@ [[NEVHEP]] is normally the event number, but may take special
values as follows:
0 the program does not keep track of event numbers.
-1 a special initialization record.
-2 a special final record.
<<HEP common: variables>>=
integer :: NEVHEP
@ %def NEVHEP
@ [[NHEP]] holds the number of entries for this event.
<<HEP common: variables>>=
integer, public :: NHEP
@ %def NHEP
@ The entry [[ISTHEP(N)]] gives the status code for the [[N]]th entry,
with the following semantics:
0 a null entry.
1 an existing entry, which has not decayed or fragmented.
2 a decayed or fragmented entry, which is retained for
event history information.
3 documentation line.
4- 10 reserved for future standards.
11-200 at the disposal of each model builder.
201- at the disposal of users.
<<HEP common: variables>>=
integer, dimension(NMXHEP), public :: ISTHEP

The Particle Data Group has proposed standard particle codes,
which are to be stored in [[IDHEP(N)]].
<<HEP common: variables>>=
integer, dimension(NMXHEP), public :: IDHEP
@ %def IDHEP
@ [[JMOHEP(1,N)]] points to the mother of the [[N]]th entry, if any.
It is set to zero for initial entries.
[[JMOHEP(2,N)]] points to the second mother, if any.
<<HEP common: variables>>=
integer, dimension(2, NMXHEP), public :: JMOHEP
@ %def JMOHEP
@ [[JDAHEP(1,N)]] and [[JDAHEP(2,N)]] point to the first and last daughter

yet decayed. The other daughters are stored in between these two.
<<HEP common: variables>>=
integer, dimension(2, NMXHEP), public :: JDAHEP
@ %def JDAHEP
@ In [[PHEP]] we store the momentum of the particle, more specifically
this means that [[PHEP(1,N)]], [[PHEP(2,N)]], and [[PHEP(3,N)]] contain the
momentum in the $x$, $y$, and $z$ direction (as defined by the machine
people), measured in GeV/c. [[PHEP(4,N)]] contains the energy in GeV
and [[PHEP(5,N)]] the mass in GeV$/c^2$. The latter may be negative for
spacelike partons.
<<HEP common: variables>>=
double precision, dimension(5, NMXHEP), public :: PHEP
@ %def PHEP
@ Finally [[VHEP]] is the place to store the position of the production
vertex. [[VHEP(1,N)]], [[VHEP(2,N)]], and [[VHEP(3,N)]] contain the $x$, $y$,
and $z$ coordinate (as defined by the machine people), measured in mm.
[[VHEP(4,N)]] contains the production time in mm/c.
<<HEP common: variables>>=
double precision, dimension(4, NMXHEP) :: VHEP

@ As an amendment to the proposed standard common block HEPEVT, we
also have a polarisation common block HEPSPN, as described in
AKV89. [[SHEP(1,N)]], [[SHEP(2,N)]], and [[SHEP(3,N)]] give the $x$, $y$, and $z$
component of the spinvector $s$ of a fermion in the fermions restframe.
Furthermore, we add the polarization of the corresponding outgoing
particles:

irrelevant.

that case, cut off the upper bits since [[NEVHEP]] is probably limited

@ This routine writes event output according to the HEPEVT standard. It
uses the current contents of the HEPEVT block and some additional
parameters according to the standard in WHIZARD 1. For the long ASCII
format, the value of the sample function (i.e. the product of squared
matrix element, structure functions and phase space factor is printed out).
The option of reweighting matrix elements with respect to some
reference cross section is not implemented in WHIZARD 2 for this event
format, therefore the second entry in the long ASCII format (the
function ratio) is always one. The ATHENA format is an implementation
of the HEPEVT format that is readable by the ATLAS ATHENA software
framework. It is very similar to the WHIZARD 1 HEPEVT format, except
that it contains an event counter, a particle counter inside the
event, and has the HEPEVT [[ISTHEP]] status before the PDG code. The
MOKKA format is a special ASCII format that contains the information
to be parsed to the MOKKA LC fast simulation software.

\subsection{Data Transfer: particle sets}
The \whizard\ format for handling particle data in events is
[[particle_set_t]]. We have to interface this to the common blocks.
We first create a new particle set that contains only the particles
that are supported by the LHEF format. These are: beam, incoming,
resonant, outgoing. We drop particles with unknown, virtual or
beam-remnant status.
From this set we fill the common block. Event information such as
process ID and weight is not transferred here; this has to be done by
the caller. The spin information is set only if the particle has a
unique mother, and if its polarization is fully defined.
We use this routine also to hand over information to Pythia which lets
Tauola access SPINUP. Tauola expects in SPINUP the helicity and not the
LHA convention. We switch to this mode with [[tauola_convention]].

two particles should be the incoming partons.

The HEPEVT common block is quite similar, but does contain less
information, e.g. no color flows (it was LEP time). The spin
information is set only if the particle has a unique mother, and if
its polarization is fully defined.

\section{HepMC events}
This section provides the interface to the HepMC C++ library for handling
Monte-Carlo events.
Each C++ class of HepMC that we use is mirrored by a Fortran type,
which contains as its only component the C pointer to the C++ object.
Each C++ method of HepMC that we use has a C wrapper function. This
function takes a pointer to the host object as its first argument.
Further arguments are either C pointers, or in the case of simple
types (integer, real), interoperable C/Fortran objects.
The C wrapper functions have explicit interfaces in the Fortran
module. They are called by Fortran wrapper procedures. These are
treated as methods of the corresponding Fortran type.

\subsection{FourVector}
The C version of four-vectors is often transferred by value, and the
associated procedures are all inlined. The wrapper needs to transfer
by reference, so we create FourVector objects on the heap which have
to be deleted explicitly. The input is a [[vector4_t]] or
[[vector3_t]] object from the [[lorentz]] module.

@ In the C constructor, the zero-component (fourth argument) is
optional; if missing, it is set to zero. The Fortran version has
initializer form and takes either a three-vector or a four-vector.
A further version extracts the four-vector from a HepMC particle
object.

\subsection{Polarization}
Polarization objects are temporarily used for assigning particle
polarization. We add a flag [[polarized]]. If this is false, the
polarization is not set and should not be transferred to
[[hepmc_particle]] objects.
<<HepMC interface: public>>=
public :: hepmc_polarization_t
<<HepMC interface: types>>=
type :: hepmc_polarization_t
private
logical :: polarized = .false.
type(c_ptr) :: obj
end type hepmc_polarization_t
@ %def hepmc_polarization_t
@ Constructor. The C wrapper takes polar and azimuthal angle as
arguments. The Fortran version allows for either a complete
polarization density matrix, or for a definite (diagonal) helicity.
\emph{HepMC does not allow to specify the degree of polarization,
therefore we have to map it to either 0 or 1. We choose 0 for
polarization less than $0.5$ and 1 for polarization greater than
$0.5$. Even this simplification works only for spin-1/2 and for
massless particles; massive vector bosons cannot be treated this
way. In particular, zero helicity is always translated as
unpolarized.}
\emph{For massive vector bosons, we arbitrarily choose the convention
that the longitudinal (zero) helicity state is mapped to the theta
angle $\pi/2$. This works under the condition that helicity is
projected onto one of the basis states.}

This test example is an abridged version from the build-from-scratch
example in the HepMC distribution. We create two vertices for $p\to
q$ PDF splitting, then a vertex for a $qq\to W^-g$ hard-interaction
process, and finally a vertex for $W^-\to qq$ decay. The setup is for
LHC kinematics.
Extending the original example, we set color flow for the incoming
quarks and polarization for the outgoing photon. For the latter, we
have to define a particle-data object for the photon, so a flavor
object can be correctly initialized.

\section{LCIO events}
This section provides the interface to the LCIO C++ library for handling
Monte-Carlo events.
Each C++ class of LCIO that we use is mirrored by a Fortran type,
which contains as its only component the C pointer to the C++ object.
Each C++ method of LCIO that we use has a C wrapper function. This
function takes a pointer to the host object as its first argument.
Further arguments are either C pointers, or in the case of simple
types (integer, real), interoperable C/Fortran objects.
The C wrapper functions have explicit interfaces in the Fortran
module. They are called by Fortran wrapper procedures. These are
treated as methods of the corresponding Fortran type.

\subsection{Polarization}
For polarization there is a three-component float entry foreseen in the LCIO
format. Completely generic density matrices can in principle be attached to
events as float vectors added to [[LCCollection]] of the [[LCEvent]]. This is
not yet implemented currently. Here, we restrict ourselves to the same
implementation as in HepMC format: we use two entries as the polarization
angles, while the first entry gives the degree of polarization (something
not specified in the HepMC format).
\emph{For massive vector bosons, we arbitrarily choose the convention
that the longitudinal (zero) helicity state is mapped to the theta
angle $\pi/2$. This works under the condition that helicity is
projected onto one of the basis states.}

\subsubsection{HepMC format}
The master output function fills a HepMC GenEvent object that is
already initialized, but has no vertices in it.
We first set up the vertex lists and enter the vertices into the HepMC
event. Then, we assign first all incoming particles and then all
outgoing particles to their associated vertices. Particles which have
neither parent nor children entries (this should not happen) are
dropped.
Finally, we insert the beam particles. If there are none, use the incoming
particles instead.
@ Transform a particle into a [[hepmc_particle]] object, including
color and polarization. The HepMC status is equivalent to the HEPEVT
status, in particular: 0 = null entry, 1 = physical particle, 2 =
decayed/fragmented SM hadron, tau or muon, 3 = other unphysical particle
entry, 4 = incoming particles, 11 = intermediate resonance such as squarks.
The use of 11 for intermediate resonances is as done by HERWIG, see
http://herwig.hepforge.org/trac/wiki/FaQs.

\subsubsection{LCIO event format}
The master output function fills a LCIO event object that is
already initialized, but has no particles in it.
In contrast to HepMC in LCIO there are no vertices (except for tracker
and other detector specifications). So we assign first all incoming
particles and then all outgoing particles to LCIO particle types.
Particles which have neither parent nor children entries (this
should not happen) are dropped. Finally, we insert the beam particles.
If there are none, use the incoming particles instead.
Transform a particle into a [[lcio_particle]] object, including
color and polarization. The LCIO status is equivalent to the HepMC
status, in particular: 0 = null entry, 1 = physical particle, 2 =
decayed/fragmented SM hadron, tau or muon, 3 = other unphysical particle
entry, 4 = incoming particles, 11 = intermediate resonance such as squarks.
The use of 11 for intermediate resonances is as done by HERWIG, see
http://herwig.hepforge.org/trac/wiki/FaQs.
A beam-remnant particle (e.g., ISR photon) that has no children is
tagged as outgoing, otherwise unphysical.

\subsection{Version-Specific Code: 1.0}
In version 1.0, the init tag contains just HEPRUP data. While a
[[cstream]] is connected to the input unit, we bypass it temporarily
for the purpose of reading the HEPRUP contents. This is consistent
with the LHEF standard.
This routine does not read the closing tag of the init block.

\subsection{Version-Specific Code: 2.0}
This is the init information for the 2.0 format, after the HEPRUP
data. We have the following tags:
\begin{itemize}
\item \texttt{generator} Generator name and version.
\item \texttt{xsecinfo} Cross section and weights data. We have the
total cross section and number of events (assuming that the event
file is intact), but information on minimum and maximum weights is
not available before the file is complete. We just write the
mandatory tags. (Note that the default values of the other tags
describe a uniform unit weight, but we can determine most values
only after the sample is complete.)
\item \texttt{cutsinfo} This optional tag is too specific to represent the
possibilities of WHIZARD, so we skip it.
\item \texttt{procinfo} This optional tag is useful for giving
details of NLO calculations. Skipped.
\item \texttt{mergetype} Optional, also not applicable.

\subsection{Version-Specific Code: 3.0}
This is the init information for the 3.0 format, after the HEPRUP
data. We have the following tags:
\begin{itemize}
\item \texttt{generator} Generator name and version.
\item \texttt{xsecinfo} Cross section and weights data. We have the
total cross section and number of events (assuming that the event
file is intact), but information on minimum and maximum weights is
not available before the file is complete. We just write the
mandatory tags. (Note that the default values of the other tags
describe a uniform unit weight, but we can determine most values
only after the sample is complete.)
\item \texttt{cutsinfo} This optional tag is too specific to represent the
possibilities of WHIZARD, so we skip it.
\item \texttt{procinfo} This optional tag is useful for giving
details of NLO calculations. Skipped.
\item \texttt{weightinfo} Determine the meaning of optional weights, whose
values are given in the event record.
\end{itemize}

@ This is additional event-specific information for the 3.0 format,
after the HEPEUP data. We can specify weights, starting from the
master weight and adding alternative weights. The weight tags are
already allocated, so we just have to transfer the weight values to
strings, assemble them and write them to file. All weights are
collected in a single tag.
Note: If efficiency turns out to be an issue, we may revert to
traditional character buffer writing. However, we need to know the
maximum length.

\subsection{Type}
A type [[hepmc_event]] is introduced as container to store HepMC event
data, particularly for splitting the reading into read out of the process
index and the proper event data.
Note: the [[keep_beams]] flag is not supported. Beams will always
be written. Tools like \texttt{Rivet} can use the cross section
information of a HepMC file for scaling plots. As there is no header in
HepMC and this is written for every event, we make it optional with
[[output_cross_section]].

\section{LCIO Output}
The LCIO event record is standardized for the use with Linear $e^+e^-$
colliders. It is a binary event format. We try our best at using it
for both input and output.

\subsection{Type}
A type [[lcio_event]] is introduced as container to store LCIO event
data, particularly for splitting the reading into read out of the process
index and the proper event data.
Note: the [[keep_beams]] flag is not supported.
