The AbstractSSTVertex class is the base class for scalar-scalar-tensor interactions in ThePEG.
The VVTVertexclass is the implementation of the scalar-scalar-tensor vertex.
Definition: SSTVertex.h:41
Complex evaluate(Energy2 q2, const ScalarWaveFunction &sca1, const ScalarWaveFunction &sca2, const TensorWaveFunction &ten3)
Members to calculate the helicity amplitude expressions for vertices and off-shell particles.
virtual void setCoupling(Energy2 q2, tcPDPtr part1, tcPDPtr part2, tcPDPtr part3)=0
Set coupling methods.
SSTVertex & operator=(const SSTVertex &)=delete
Private and non-existent assignment operator.
static void Init()
Standard Init function used to initialize the interfaces.
ScalarWaveFunction evaluate(Energy2 q2, int iopt, tcPDPtr out, const ScalarWaveFunction &sca1, const TensorWaveFunction &ten3, complex< Energy > mass=-GeV, complex< Energy > width=-GeV)
Evaluate the off-shell scalar coming from the vertex.
