Implementation of the ReggeonPDF PDFs.
Definition: ReggeonPDF.h:31
virtual IBPtr fullclone() const
Make a clone of this object, possibly modifying the cloned object to make it sane.
virtual double xfvx(tcPDPtr particle, tcPDPtr parton, Energy2 partonScale, double x, double eps=0.0, Energy2 particleScale=ZERO) const
Return x times the valence pdf for the given parameters.
void persistentInput(PersistentIStream &is, int version)
Function used to read in object persistently.
virtual void doinit()
Initialize this object after the setup phase before saving an EventGenerator to disk.
PDFPtr ptrPDF_
Pointer to the concrete PDF reggeon structure function.
Definition: ReggeonPDF.h:151
virtual cPDVector partons(tcPDPtr p) const
Return the parton types which are described by these parton densities.
PDPtr particle_
Pointer to the particle.
Definition: ReggeonPDF.h:161
virtual double xfx(tcPDPtr particle, tcPDPtr parton, Energy2 partonScale, double x, double eps=0.0, Energy2 particleScale=ZERO) const
Return x times the pdf for the given parameters.
ReggeonPDF & operator=(const ReggeonPDF &)=delete
The assignment operator is private and must never be called.
long particleID_
PDG code for the particle.
Definition: ReggeonPDF.h:156
void persistentOutput(PersistentOStream &os) const
Function used to write out object persistently.
virtual IBPtr clone() const
Make a simple clone of this object.
static void Init()
The standard Init function used to initialize the interfaces.
ReggeonPDF()
Default constructor.
Definition: ReggeonPDF.h:38
virtual bool canHandleParticle(tcPDPtr particle) const
Return true if this PDF can handle the extraction of parton from the given particle ie.
