Detailed Description

This class corresponds to a kinematical cut to be made on a set of outgoing particles from a hard sub-process.

There are three virtual functions to be overridden by concrete sub-classes. minS() and maxS() should return the minimum and maximum invariant mass of of a set of particle types. In addition the passCut() function should return true if a set of particle with a given types and given momenta will pass the cuts.

Member Function Documentation

◆ Init()

static void ThePEG::MultiCutBase::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.

◆ maxS()

virtual Energy2 ThePEG::MultiCutBase::maxS ( const tcPDVector pv) const
virtual

Return the maximum allowed value of the squared invariant mass of a set of outgoing partons of the given types.

Typically used to cut off the tails of the mass of a resonance for efficiency.

Reimplemented in ThePEG::V2LeptonsCut.

◆ minS()

virtual Energy2 ThePEG::MultiCutBase::minS ( const tcPDVector pv) const
virtual

Return the minimum allowed value of the squared invariant mass of a set of outgoing partons of the given types.

Typically used to cut off the tails of the mass of a resonance for efficiency.

Reimplemented in ThePEG::V2LeptonsCut.

◆ operator=()

MultiCutBase& ThePEG::MultiCutBase::operator= ( const MultiCutBase )
privatedelete

The assignment operator is private and must never be called.

In fact, it should not even be implemented.

Member Data Documentation

◆ initMultiCutBase

AbstractNoPIOClassDescription<MultiCutBase> ThePEG::MultiCutBase::initMultiCutBase
staticprivate

The static object used to initialize the description of this class.

Indicates that this is an abstract class without persistent data.
