2001-08-01
Default whizard.prc and whizard.in depend on activated modules
Fixed bug: TEX=latex was not properly enabled when making plots
2001-07-20
Fixed output settings in PERL script calls
Cache enabled in various configure checks
2001-07-13
Support for multiple processes in a single WHIZARD run. The
integrations are kept separate, but the generated events are mixed
The whizard.evx format has changed (incompatible), including now
the color flow information for PYTHIA fragmentation
Output files are now process-specific, except for the event file
Phase space file whizard.phs (if present) is used only as input,
program-generated phase space is now in whizard.phx

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

!!! NOTE (Akiya Miyamoto, 25-March-2016)
!!! Higgs (h0/H0/A0) to tau+tau- decay is handled here
!!! in order to implement a transverse spin correlation.
!!! For this algorithm to work, photon emission from tau
!!! before decay should be turned off. Since photon emission
!!! from tau is handled by PYTHIA, photon emission from ALL tau
!!! should be turned off. It is done by setting MSTJ(39)=15.
!!! Instead, PHOTOS is called after tau decay and generate
!!! photons.

!...PYTAUD
!...Routine to handle the decay of a polarized tau lepton.
!...Input:
!...ITAU is the position where the decaying tau is stored in /PYJETS/.
!...IORIG is the position where the mother of the tau is stored;
!... is 0 when the mother is not stored.
!...KFORIG is the flavour of the mother of the tau;
!... is 0 when the mother is not known.
!...Note that IORIG=0 does not necessarily imply KFORIG=0;
!... e.g. in B hadron semileptonic decays the W propagator
!... is not explicitly stored but the W code is still unambiguous.
!...Output:
!...NDECAY is the number of decay products in the current tau decay.
!...These decay products should be added to the /PYJETS/ common block,
!...in positions N+1 through N+NDECAY. For each product I you must
!...give the flavour codes K(I,2) and the five-momenta P(I,1), P(I,2),
!...P(I,3), P(I,4) and P(I,5). The rest will be stored automatically.
