Detailed Description

LeptonLeptonPDF inherits from PDFBase and encodes the distribution of leptons within leptons, ie.

Member Function Documentation

virtual bool ThePEG::LeptonLeptonPDF::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 lepton.

Implements ThePEG::PDFBase.

virtual bool ThePEG::LeptonLeptonPDF::hasPoleIn1	(	tcPDPtr	particle,
		tcPDPtr	parton
	)			const [virtual]

Return true if this PDF has a pole at $x=1$ for the given particle and parton.

Returns true if parton and particle are the same.

Reimplemented from ThePEG::PDFBase.

virtual double ThePEG::LeptonLeptonPDF::xfvl	(	tcPDPtr	particle,
		tcPDPtr	parton,
		Energy2	partonScale,
		double	l,
		Energy2	particleScale = ZERO
	)			const [virtual]

Return the the valens part of the true pdf for the given parameters, with the momentum fraction given as l.

This version simply returns the full pdf.

Reimplemented from ThePEG::PDFBase.

virtual double ThePEG::LeptonLeptonPDF::xfvx	(	tcPDPtr	particle,
		tcPDPtr	parton,
		Energy2	partonScale,
		double	x,
		double	eps,
		Energy2	particleScale
	)			const [virtual]

Return the the valens part of the true pdf for the given parameters, with the momentum fraction given as x.

This version simply returns the full pdf.

Reimplemented from ThePEG::PDFBase.

virtual double ThePEG::LeptonLeptonPDF::flattenL	(	tcPDPtr	particle,
		tcPDPtr	parton,
		const PDFCuts &	,
		double	z,
		double &	jacobian
	)			const [virtual]

If the PDF contains strange peaks which can be difficult to handle, this function may be overwritten to return an appropriate l for a z given by a flat distribution in ]0,1[.

Also the jacobobian of the l(z) function must be returned. The default version will simly use the function l(z) = lmin + z*(lmax-lmin).

Reimplemented from ThePEG::PDFBase.

virtual IBPtr ThePEG::LeptonLeptonPDF::clone

(

)

const [protected, virtual]

Make a simple clone of this object.

Returns:

a pointer to the new object.

Implements ThePEG::InterfacedBase.

virtual IBPtr ThePEG::LeptonLeptonPDF::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.
