Member Function Documentation

◆ canHandleParticle()

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

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

if the particle is a proton or neutron.

Parameters
particleThe particle

Implements ThePEG::PDFBase.

◆ clone()

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

Make a simple clone of this object.

Returns
a pointer to the new object.

Implements ThePEG::InterfacedBase.

◆ doinit()

virtual void Herwig::PomeronPDF::doinit ( )
protectedvirtual

Initialize this object after the setup phase before saving an EventGenerator to disk.

Exceptions
InitExceptionif object could not be initialized properly.

Reimplemented from ThePEG::PDFBase.

◆ fullclone()

virtual IBPtr Herwig::PomeronPDF::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.

◆ getPDFValue()

double Herwig::PomeronPDF::getPDFValue ( PDFFlavour  flPDF,
double  x,
Energy2  qq 
) const
private

This function calculates the PDF value for the given particles and a given x and q.

Parameters
flPDFFlavour of the PDF function
xThe x of the pomeron
qqThe scale

◆ Init()

static void Herwig::PomeronPDF::Init ( )
static

The standard Init function used to initialize the interfaces.

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

◆ persistentOutput()

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

Function used to write out object persistently.

Parameters
osthe persistent output stream written to.

◆ xfvx()

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

Return x times the valence pdf for the given parameters.

Parameters

Reimplemented from ThePEG::PDFBase.

◆ xfx()

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

Return x times the pdf for the given parameters.

Parameters
