Detailed Description

The OmegaPhi3PiDecayer class inherits from performs FlatDecayer and will reweight the flat phase space suitable to describe the decay of a $\phi$ or an $\omega$ into $\pi^+\pi^-\pi^0$ .

It will in fact decay anything into $\pi^+\pi^-\pi^0$ assuming the same matrix element.

Member Function Documentation

virtual bool ThePEG::OmegaPhi3PiDecayer::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::FlatDecayer.

virtual double ThePEG::OmegaPhi3PiDecayer::reweight	(	const DecayMode &	dm,
		const Particle &	parent,
		const ParticleVector &	children
	)			const `[virtual]`

Give a weight to a phase space point.

To be overridden by subclasses. For a given decay mode, dm, decaying parent particle and decayproducts, children, distributed according to a flat distribution in phase space, return a weight (less or equal to unity) modifying the flat distribution to the desired one. Note that the chosen phase space point may be rejected, but the chosen decay channel will not. This means that the weight returned by this function does not influence the branching ratios.

Reimplemented from ThePEG::FlatDecayer.

void ThePEG::OmegaPhi3PiDecayer::persistentOutput ( PersistentOStream & os ) const

Function used to write out object persistently.

Parameters:

os

the persistent output stream written to.

Reimplemented from ThePEG::Decayer.

void ThePEG::OmegaPhi3PiDecayer::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::Decayer.

virtual IBPtr ThePEG::OmegaPhi3PiDecayer::clone ( ) const [protected, virtual]

Make a simple clone of this object.

Returns:: a pointer to the new object.

Reimplemented from ThePEG::FlatDecayer.

virtual IBPtr ThePEG::OmegaPhi3PiDecayer::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::FlatDecayer.

Member Data Documentation

double ThePEG::OmegaPhi3PiDecayer::margin [private]

Used to multiply the bare weight to get something below unity.

In the Fortran pythia version it was set to 150 for unknown reasons.
