Detailed Description

Objects of the MadGraphOneCut class can be created automatically by the MadGraphReader class when scanning event files for information about cuts.

It is also possible to create objects by hand and use it as any other OneCutBase object.

Member Function Documentation

virtual double ThePEG::MadGraphOneCut::minEta ( tcPDPtr p ) const [virtual]

Return the minimum allowed pseudo-rapidity of an outgoing parton of the given type.

The pseudo-rapidity is measured in the lab system.

Implements ThePEG::OneCutBase.

virtual double ThePEG::MadGraphOneCut::maxEta ( tcPDPtr p ) const [virtual]

Return the maximum allowed pseudo-rapidity of an outgoing parton of the given type.

The pseudo-rapidity is measured in the lab system.

Implements ThePEG::OneCutBase.

virtual Energy ThePEG::MadGraphOneCut::minMaxKT ( tcPDPtr p ) const [virtual]

Return the minimum allowed value of the transverse momentum of the outgoing parton with the lagrest transverse momentum.

This version simply returns minKt().

Reimplemented from ThePEG::OneCutBase.

virtual bool ThePEG::MadGraphOneCut::passCuts	(	tcCutsPtr	parent,
		tcPDPtr	ptype,
		LorentzMomentum	p
	)			const `[virtual]`

Return true if a particle with type ptype and momentum p passes the cuts.

The parent contains information about the kinematics of the hard sub-process.

Reimplemented from ThePEG::OneCutBase.

void ThePEG::MadGraphOneCut::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::MadGraphOneCut::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::MadGraphOneCut::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::OneCutBase.

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

Make a simple clone of this object.

Returns:: a pointer to the new object.

Implements ThePEG::InterfacedBase.

virtual IBPtr ThePEG::MadGraphOneCut::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.

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

The assignment operator is private and must never be called.

In fact, it should not even be implemented.
