* This method does the splitting of the cluster pointed by cluPtr

* new children clusters are added (indeed the pointers to them) to the
* collection of cluster pointers collecCluPtr. The method works as follows.
* Initially the vector vecCluPtr contains just the input pointer to the
* cluster to be split. Then it will be filled "recursively" by all
* of the cluster's children that are heavy enough to require, in their turn,
* to be split. In each loop, the last element of the vector vecCluPtr is
* considered (only once because it is then removed from the vector).
* This approach is conceptually recursive, but avoid the overhead of
* a concrete recursive function. Furthermore it requires minimal changes
* in the case that the fission of an heavy cluster could produce more
* than two cluster children as assumed now.
*
* Draw the masses: for normal, non-beam clusters a power-like mass dist
* is used, whereas for beam clusters a fast-decreasing exponential mass
* dist is used instead (to avoid many iterative splitting which could
* produce an unphysical large transverse energy from a supposed soft beam
* remnant process).

* cluster child and one single hadron child. We prefer this approach,
* rather than to create a light cluster, with the mass set equal to
* the lightest hadron, and let then the class LightClusterDecayer to do
* the job to decay it to that single hadron, for two reasons:
* First, because the sum of the masses of the two constituents can be,
* in this case, greater than the mass of that hadron, hence it would
* be impossible to solve the kinematics for such two components, and
* therefore we would have a cluster whose components are undefined.
* Second, the algorithm is faster, because it avoids the reshuffling
* procedure that would be necessary if we used LightClusterDecayer
* to decay the light cluster to the lightest hadron.

* case the cluster itself is identify with that hadron) and we do
* not have to solve the kinematics of the components (Q1,Qbar) for
* C1 and (Q,Q2bar) for C2.
* The output is given by the following momenta (all 5-components,
* and all in the LAB frame):
* pClu1 , pClu2 respectively of C1 , C2
* pQ1 , pQbar respectively of Q1 , Qbar in C1
* pQ , pQ2bar respectively of Q , Q2 in C2
* The assumption, suggested from the string model, is that, in C frame,
* C1 and its constituents Q1 and Qbar are collinear, and collinear to
* the direction of Q1 in C (that is before cluster decay); similarly,
* (always in the C frame) C2 and its constituents Q and Q2bar are
* collinear (and therefore anti-collinear with C1,Q1,Qbar).
* The solution is then obtained by using Lorentz boosts, as follows.
* The kinematics of C1 and C2 is solved in their parent C frame,
* and then boosted back in the LAB. The kinematics of Q1 and Qbar
* is solved in their parent C1 frame and then boosted back in the LAB;
* similarly, the kinematics of Q and Q2bar is solved in their parent
* C2 frame and then boosted back in the LAB. In each of the three
* "two-body decay"-like cases, we use the fact that the direction
* of the motion of the decay products is known in the rest frame of
* their parent. This is obvious for the first case in which the
* parent rest frame is C; but it is also true in the other two cases
* where the rest frames are C1 and C2. This is because C1 and C2
* are boosted w.r.t. C in the same direction where their components,
* respectively (Q1,Qbar) and (Q,Q2bar) move in C1 and C2 rest frame
* respectively.
* Of course, although the notation used assumed that C = (Q1 Q2bar)
* where Q1 is a quark and Q2bar an antiquark, indeed everything remain
* unchanged also in all following cases:
* Q1 quark, Q2bar antiquark; --> Q quark;
* Q1 antiquark , Q2bar quark; --> Q antiquark;
* Q1 quark, Q2bar diquark; --> Q quark
* Q1 antiquark, Q2bar anti-diquark; --> Q antiquark
* Q1 diquark, Q2bar quark --> Q antiquark
* Q1 anti-diquark, Q2bar antiquark; --> Q quark

/** \ingroup Hadronization
* \class ClusterFissioner
* \brief This class handles clusters which are too heavy.
* \author Philip Stephens
* \author Alberto Ribon
* \author Stefan Gieseke
*
* This class does the job of chopping up either heavy clusters or beam
* clusters in two lighter ones. The procedure is repeated recursively until
* all of the cluster children have masses below some threshold values.
*
* For the beam remnant clusters, at the moment what is done is the following.
* In the case that the soft underlying event is switched on, the
* beam remnant clusters are tagged as not available,
* therefore they will not be treated at all during the hadronization.
* In the case instead that the soft underlying event is switched off,
* then the beam remnant clusters are treated exactly as "normal" clusters,
* with the only exception of the mass spectrum used to generate the
* cluster children masses. For non-beam clusters, the masses of the cluster
* children are draw from a power-like mass distribution; for beam clusters,
* according to the value of the flag _IOpRem, either both
* children masses are draw from a fast-decreasing exponential mass
* distribution (case _IOpRem == 0, or, indendently by
* _IOpRem, in the special case that the beam cluster contains two
* beam remnants), or one mass from the exponential distribution (corresponding
* of the cluster child with the beam remnant) and the other with the usual
* power-like distribution (case _IOpRem == 1, which is the
* default one, as in Herwig 6.3).
*
* The reason behind the use of a fast-decreasing exponential distribution
* is that to avoid a large transverse energy from the many sequential
* fissions that would otherwise occur due to the typical large cluster
* mass of beam clusters. Using instead an exponential distribution
* the masses of the two cluster children will be very small (order of
* GeV).
*
* The rationale behind the implementation of the splitting of clusters
* has been to preserve *all* of the information about such splitting
* process. More explicitly a ThePEG::Step class is passed in and the
* new clusters are added to the step as the decay products of the
* heavy cluster. This approach has the twofold
* advantage to provide all of the information that could be needed
* (expecially in future developments), without any information loss,
* and furthermore it allows a better debugging.
*
* @see HadronSelector
* @see \ref ClusterFissionerInterfaces "The interfaces"
* defined for ClusterFissioner.

* where \f$ M \f$ is the clusters mass, \f$ P \f$ is the parameter
* ClPow, \f$ C \f$ is the parameter ClMax and \f$ S \f$ is the
* sum of the clusters constituent partons.
* For beam clusters, they are split only if the soft underlying event
* is switched off, otherwise these clusters will be tagged as unavailable
* and they will not be treated by the hadronization altogether.
* In the case beam clusters will be split, the procedure is exactly
* the same as for normal non-beam clusters, with the only exception
* of the mass spectrum from which to draw the masses of the two
* cluster children (see method drawChildrenMasses for details).

* Initially the vector contains just the stack of input pointers to the

* to be split. In each loop, the last element of the vector is

*
* \todo is the following still true?
* For normal, non-beam clusters, a power-like mass distribution
* is used, whereas for beam clusters a fast-decreasing exponential mass
* distribution is used instead. This avoids many iterative splitting which
* could produce an unphysical large transverse energy from a supposed

* \f[M_p=M_n=M_\Delta\f]
* and we will have equal numbers of u and d quarks produced.
* Suppose that we weight 1 the diquarks made of the same
* quark and 1/2 those made of different quarks, the fractions
* of u and d baryons (p, n, Delta) we get are the following:
* - \f$\Delta^{++}\f$: 1 possibility only u uu with weight 1
* - \f$\Delta^- \f$: 1 possibility only d dd with weight 1
* - \f$p,\Delta^+ \f$: 2 possibilities u ud with weight 1/2
* d uu with weight 1
* - \f$n,\Delta^0 \f$: 2 possibilities d ud with weight 1/2
* u dd with weight 1
* In the latter two cases, we have to take into account the
* fact that p and n have spin 1/2 whereas Delta+ and Delta0
* have spin 3/2 therefore from phase space we get a double weight
* for Delta+ and Delta0 relative to p and n respectively.
* Therefore the relative amount of these baryons that is
* produced is the following:
* # p = # n = ( 1/2 + 1 ) * 1/3 = 1/2
* # Delta++ = # Delta- = 1 = ( 1/2 + 1) * 2/3 # Delta+ = # Delta0
* which is correct, and therefore the weight 1/2 for the

* \class LightClusterDecayer
* \brief This class performs the decay of light clusters into a single hadron.
* \author Philip Stephens
* \author Alberto Ribon
*
* This is the class that performs the decay of light clusters into
* only one hadron. The major difficulty is that a kinematical reshuffling
* is necessary, between the cluster under consideration and its
* "neighbouring" clusters, to conserve energy-momentum in one-body decay.
* Notice that, differently from what happens in Fortran Herwig,
* light (that is below the threshold for the production of the lightest
* pair of hadrons with the proper flavours) fission products, produced
* by the fission of heavy clusters in ClusterFissioner
* have been already "decayed" into single hadron (the lightest one
* with proper flavour) by the same latter class, without require
* any reshuffling. Therefore the light clusters that are treated in
* this LightClusterDecayer class are produced directly
* (originally) by the ClusterFinder.
*
* Notice:
* - The choice of the candidate cluster with whom to reshuffle momentum
* is based on the minimal space-time distance from the light cluster.
* - An alternate choice of what is considered a "neighbour" could be
* implemented but was not considered for Herwig.
*
* @see HadronSelector
* @see \ref LightClusterDecayerInterfaces "The interfaces"
* defined for LightClusterDecayer.
