Detailed Description

The VVSLoopVertex is designed to calculate the coefficents for the terms in the Passarino-Veltman tensor reduction scheme.

A vertex class should inherit from this and implement it's own setCoupling member from which the VVSLoopVertex
setCoupling member is called.

Member Function Documentation

◆ clone()

virtual IBPtr Herwig::VVSLoopVertex::clone ( ) const

protectedvirtual

Make a simple clone of this object.

Returns: a pointer to the new object.

Implements ThePEG::InterfacedBase.

Reimplemented in Herwig::GenericHGGVertex, Herwig::GenericHPPVertex, Herwig::SMHGGVertex, Herwig::SMHPPVertex, Herwig::NMSSMGGHVertex, Herwig::NMSSMPPHVertex, Herwig::SSHGGVertex, and Herwig::SSHPPVertex.

◆ dofinish()

virtual void Herwig::VVSLoopVertex::dofinish ( )

protectedvirtual

Finalize this object.

Called in the run phase just after a run has ended. Used eg. to write out statistics.

Reimplemented from ThePEG::InterfacedBase.

◆ fullclone()

virtual IBPtr Herwig::VVSLoopVertex::fullclone ( ) const

protectedvirtual

Make a clone of this object, possibly modifying the cloned object to make it sane.

◆ Init()

static void Herwig::VVSLoopVertex::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.

◆ loopToolsInitialized()

bool Herwig::VVSLoopVertex::loopToolsInitialized ( )

inlineprotected

Is loopTools initialized.

Function used to read in object persistently.

Parameters

is	the persistent input stream read from.
version	the version number of the object when written.
