Member Function Documentation

◆ clone()

virtual IBPtr Herwig::ConstituentReshuffler::clone ( ) const
protectedvirtual

Make a simple clone of this object.

Returns
a pointer to the new object.

Implements ThePEG::InterfacedBase.

◆ decayReshuffle()

void Herwig::ConstituentReshuffler::decayReshuffle ( PerturbativeProcessPtr &  decayProc,
PList eventOutgoing,
PList eventHard,
PList eventIntermediates 
)

Reshuffle the outgoing partons following the showering of a particle decay to constituent masses.

Throw ConstituentReshufflerProblem if a numerical problem prevents the solution of the reshuffling equation.

◆ fullclone()

virtual IBPtr Herwig::ConstituentReshuffler::fullclone ( ) const
protectedvirtual

Make a clone of this object, possibly modifying the cloned object to make it sane.

Returns
a pointer to the new object.

Reimplemented from ThePEG::InterfacedBase.

◆ hardProcDecayReshuffle()

void Herwig::ConstituentReshuffler::hardProcDecayReshuffle ( PList decaying,
PList eventOutgoing,
PList eventHard,
PPair eventIncoming,
PList eventIntermediates 
)

Reshuffle the outgoing partons following the showering of the initial hard interaction to constituent masses, for the case of outgoing decaying particles.

Throw ConstituentReshufflerProblem if a numerical problem prevents the solution of the reshuffling equation.

◆ Init()

static void Herwig::ConstituentReshuffler::Init ( )
static

The standard Init function used to initialize the interfaces.

Called exactly once for each class by the class description system before the main function starts or when this class is dynamically loaded.

◆ operator=()

ConstituentReshuffler& Herwig::ConstituentReshuffler::operator= ( const ConstituentReshuffler )
privatedelete

The assignment operator is private and must never be called.

In fact, it should not even be implemented.

◆ persistentInput()

void Herwig::ConstituentReshuffler::persistentInput ( PersistentIStream is,
int  version 
)

Function used to read in object persistently.

Parameters
isthe persistent input stream read from.
versionthe version number of the object when written.

◆ persistentOutput()

void Herwig::ConstituentReshuffler::persistentOutput ( PersistentOStream os) const

Function used to write out object persistently.

Parameters
osthe persistent output stream written to.

◆ reshuffle() [1/2]

void Herwig::ConstituentReshuffler::reshuffle ( PList out,
PPair in,
PList intermediates,
const bool  decay,
PList decayPartons,
PList decayRecoilers 
)

Reshuffle the outgoing partons to constituent masses.

Optionally, incoming partons are given to absorb recoils. Add the non-reshuffled partons to the intermediates list. Throw ConstituentReshufflerProblem if a numerical problem prevents the solution of the reshuffling equation.

◆ reshuffle() [2/2]

void Herwig::ConstituentReshuffler::reshuffle ( PList out,
PPair in,
PList intermediates,
const bool  decay = false 
)
inline

Reshuffle the outgoing partons to constituent masses.

Optionally, incoming partons are given to absorb recoils. Add the non-reshuffled partons to the intermediates list. Throw ConstituentReshufflerProblem if a numerical problem prevents the solution of the reshuffling equation.

Definition at line 74 of file ConstituentReshuffler.h.

◆ updateSpinInfo()

void Herwig::ConstituentReshuffler::updateSpinInfo ( PPtr oldPart,
PPtr newPart 
)

Update the spinInfo of a particle following reshuffling to take account of the change in momentum.

Used only for unstable particles that need to be dealt with.
