Constructor & Destructor Documentation

◆ SatPDF()

Herwig::SatPDF::SatPDF ( )

inline

The default constructor.

Definition at line 37 of file SatPDF.h.

Member Function Documentation

◆ canHandleParticle()

virtual bool Herwig::SatPDF::canHandleParticle ( tcPDPtr particle ) const

virtual

Return true if this PDF can handle the extraction of partons from the given particle.

Implements ThePEG::PDFBase.

◆ clone()

virtual IBPtr Herwig::SatPDF::clone ( ) const

inlineprotectedvirtual

Make a simple clone of this object.

Returns: a pointer to the new object.

Implements ThePEG::InterfacedBase.

Definition at line 112 of file SatPDF.h.

◆ fullclone()

virtual IBPtr Herwig::SatPDF::fullclone ( ) const

inlineprotectedvirtual

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.

Definition at line 118 of file SatPDF.h.

◆ Init()

static void Herwig::SatPDF::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=()

SatPDF & Herwig::SatPDF::operator= ( const SatPDF & )

privatedelete

The assignment operator is private and must never be called.

In fact, it should not even be implemented.

◆ partons()

virtual cPDVector Herwig::SatPDF::partons ( tcPDPtr particle ) const

virtual

Return the partons which this PDF may extract from the given particle.

Implements ThePEG::PDFBase.

◆ persistentInput()

void Herwig::SatPDF::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.

◆ persistentOutput()

void Herwig::SatPDF::persistentOutput ( PersistentOStream & os ) const

Function used to write out object persistently.

Parameters

os	the persistent output stream written to.

◆ xfvx()

virtual double Herwig::SatPDF::xfvx	(	tcPDPtr	particle,
		tcPDPtr	parton,
		Energy2	partonScale,
		double	x,
		double	eps = `0.0`,
		Energy2	particleScale = `ZERO`
	)		const

virtual

The valence density.

Return the pdf for the given cvalence parton inside the given particle for the virtuality partonScale and momentum fraction x. The particle is assumed to have a virtuality particleScale. If not overidden by a sub class this implementation will assume that the difference between a quark and anti-quark distribution is due do valense quarks, but return zero for anything else.

Reimplemented from ThePEG::PDFBase.

◆ xfx()

virtual double Herwig::SatPDF::xfx	(	tcPDPtr	particle,
		tcPDPtr	parton,
		Energy2	partonScale,
		double	x,
		double	eps = `0.0`,
		Energy2	particleScale = `ZERO`
	)		const

virtual

The density.

Return the pdf for the given parton inside the given particle for the virtuality partonScale and momentum fraction x. The particle is assumed to have a virtuality particleScale.

Reimplemented from ThePEG::PDFBase.

private

pointer to the underlying ThePEG::PDFBase object, we are modifying.
