The SMGGGGVertex class is the implementation of the Standard Model quartic gluon vertex.
Definition: SMGGGGVertex.h:30
virtual void setCoupling(Energy2 q2, tcPDPtr part1, tcPDPtr part2, tcPDPtr part3, tcPDPtr part4)
Calculate the couplings.
static void Init()
Standard Init function used to initialize the interfaces.
SMGGGGVertex()
Default constructor.
virtual IBPtr fullclone() const
Make a clone of this object, possibly modifying the cloned object to make it sane.
Definition: SMGGGGVertex.h:69
Complex _couplast
Storage of the couplings.
Definition: SMGGGGVertex.h:98
virtual IBPtr clone() const
Make a simple clone of this object.
Definition: SMGGGGVertex.h:63
virtual void doinit()
Initialize this object after the setup phase before saving an EventGenerator to disk.
Energy2 _q2last
The scale at which the coupling was last evaluated.
Definition: SMGGGGVertex.h:103
SMGGGGVertex & operator=(const SMGGGGVertex &)=delete
Private and non-existent assignment operator.
