Member Function Documentation

virtual bool ThePEG::SimpleBaryonRemnantDecayer::accept ( const DecayMode & dm ) const [virtual]

Check if this decayer can perfom the decay specified by the given decay mode.

Parameters:

dm

the DecayMode describing the decay.

Returns:: true if this decayer can handle the given mode, otherwise false.

Reimplemented from ThePEG::RemnantDecayer.

virtual ParticleVector ThePEG::SimpleBaryonRemnantDecayer::decay	(	const DecayMode &	dm,
		const Particle &	p,
		Step &	step
	)			const `[virtual]`

Perform a decay for a given DecayMode and a given Particle instance.

This version allows the decaying particle to borrow energy/momentum from its sublings in the current step. This will be called by the standard DecayHandler if the needsFullStep() function returns true.

Parameters:

	dm	the DecayMode describing the decay.
	p	the Particle instance to be decayed.
	step	the current step in which to find possible siblings to shuffle energy with.

Returns:: a ParticleVector containing the decay products.

Implements ThePEG::RemnantDecayer.

virtual bool ThePEG::SimpleBaryonRemnantDecayer::checkExtract	(	tcPPtr	parent,
		tcPPtr	extracted,
		const LorentzMomentum &	pnew
	)			const `[virtual]`

Return true if this decayer can handle the extraction of the extracted parton instance from the given particle instance.

pnew is the momentum of the resulting remnant. The default version simply checks if the energy is positive.

Reimplemented from ThePEG::RemnantDecayer.

virtual void ThePEG::SimpleBaryonRemnantDecayer::doinit ( ) [protected, virtual]

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

Exceptions:

InitException

if object could not be initialized properly.

Reimplemented from ThePEG::RemnantDecayer.

void ThePEG::SimpleBaryonRemnantDecayer::persistentOutput ( PersistentOStream & os ) const

Function used to write out object persistently.

Parameters:

os

the persistent output stream written to.

Reimplemented from ThePEG::RemnantDecayer.

void ThePEG::SimpleBaryonRemnantDecayer::persistentInput	(	PersistentIStream &	is,
		int	version
	)

Function used to read in object persistently.

Parameters:

	is	the persistent input stream read from.
	version	the version number of the object when written.

Reimplemented from ThePEG::RemnantDecayer.

static void ThePEG::SimpleBaryonRemnantDecayer::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.

Reimplemented from ThePEG::RemnantDecayer.

virtual IBPtr ThePEG::SimpleBaryonRemnantDecayer::clone ( ) const [protected, virtual]

Make a simple clone of this object.

Returns:: a pointer to the new object.

Implements ThePEG::InterfacedBase.

virtual IBPtr ThePEG::SimpleBaryonRemnantDecayer::fullclone ( ) const [protected, virtual]

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.

SimpleBaryonRemnantDecayer& ThePEG::SimpleBaryonRemnantDecayer::operator= ( const SimpleBaryonRemnantDecayer & ) [private]

The assignment operator is private and must never be called.

In fact, it should not even be implemented.
