Member Function Documentation

◆ checkDecays()

void Herwig::ModelGenerator::checkDecays ( PDPtr  parent)
private

Check the decay modes a given particle type.

This checks whether the decay has quarks in the final state and that they can be put on mass-shell during the shower.

Parameters
parentThe parent particle

◆ clone()

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

Make a simple clone of this object.

Returns
a pointer to the new object.

Implements ThePEG::InterfacedBase.

◆ createWidthGenerator()

void Herwig::ModelGenerator::createWidthGenerator ( tPDPtr  p)
private

Create mass and width generators to simulate off-shell effects.

Parameters
pA pointer to the ParticleData object to create the width and mass generators for.

◆ doinit()

virtual void Herwig::ModelGenerator::doinit ( )
protectedvirtual

Initialize this object after the setup phase before saving an EventGenerator to disk.

Exceptions
InitExceptionif object could not be initialized properly.

Reimplemented from ThePEG::InterfacedBase.

◆ fullclone()

virtual IBPtr Herwig::ModelGenerator::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.

◆ Init()

static void Herwig::ModelGenerator::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=()

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

The assignment operator is private and must never be called.

In fact, it should not even be implemented.

◆ persistentInput()

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

Function used to write out object persistently.

Parameters
osthe persistent output stream written to.

Member Data Documentation

◆ Offsel_

int Herwig::ModelGenerator::Offsel_
private

Which particles to treat as off-shell.

1 treats all particles in particles_ vector as off-shell, 0 allows selection via offshell_ vector.
