Member Function Documentation

virtual Energy2 ThePEG::V2LeptonsCut::minS ( const tcPDVector & pv ) const [virtual]

Return the minimum allowed value of the squared invariant mass of a set of outgoing partons of the given types.

Typically used to cut off the tails of the mass of a resonance for efficiency.

Implements ThePEG::MultiCutBase.

virtual Energy2 ThePEG::V2LeptonsCut::maxS ( const tcPDVector & pv ) const [virtual]

Return the maximum allowed value of the squared invariant mass of a set of outgoing partons of the given types.

Typically used to cut off the tails of the mass of a resonance for efficiency.

Implements ThePEG::MultiCutBase.

void ThePEG::V2LeptonsCut::persistentOutput ( PersistentOStream & os ) const

Function used to write out object persistently.

Parameters:

os

the persistent output stream written to.

Reimplemented from ThePEG::Interfaced.

void ThePEG::V2LeptonsCut::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::Interfaced.

static void ThePEG::V2LeptonsCut::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::MultiCutBase.

virtual IBPtr ThePEG::V2LeptonsCut::clone ( ) const [protected, virtual]

Make a simple clone of this object.

Returns:: a pointer to the new object.

Implements ThePEG::InterfacedBase.

virtual IBPtr ThePEG::V2LeptonsCut::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.

V2LeptonsCut& ThePEG::V2LeptonsCut::operator= ( const V2LeptonsCut & ) [private]

The assignment operator is private and must never be called.

In fact, it should not even be implemented.
