Member Function Documentation

◆ clone()

virtual IBPtr Herwig::MPIPDF::clone ( ) const
protectedvirtual

Make a simple clone of this object.

Returns
a pointer to the new object.

Implements ThePEG::InterfacedBase.

◆ fullclone()

virtual IBPtr Herwig::MPIPDF::fullclone ( ) const
protectedvirtual

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.

◆ Init()

static void Herwig::MPIPDF::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=()

MPIPDF& Herwig::MPIPDF::operator= ( const MPIPDF )
privatedelete

The assignment operator is private and must never be called.

In fact, it should not even be implemented.

◆ persistentInput()

void Herwig::MPIPDF::persistentInput ( PersistentIStream is,
int  version 
)

Function used to read in object persistently.

Parameters
isthe persistent input stream read from.
versionthe version number of the object when written.

◆ persistentOutput()

void Herwig::MPIPDF::persistentOutput ( PersistentOStream os) const

Function used to write out object persistently.

Parameters
osthe persistent output stream written to.

◆ xfvx()

virtual double Herwig::MPIPDF::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::MPIPDF::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. For MPIPDF, only the sea quark densities are included here!

Reimplemented from ThePEG::PDFBase.
