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.

Make a simple clone of this object.
Implements ThePEG::InterfacedBase.
Reimplemented in Herwig::GenericHPPVertex, Herwig::GenericHGGVertex, Herwig::SSHGGVertex, Herwig::SMHPPVertex, Herwig::SSHPPVertex, Herwig::NMSSMGGHVertex, Herwig::NMSSMPPHVertex, and Herwig::SMHGGVertex.

Called in the run phase just after a run has ended. Used eg. to write out statistics.
Reimplemented from ThePEG::InterfacedBase.

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.
|
privatedelete |
The assignment operator is private and must never be called.
In fact, it should not even be implemented.
