Here is the documentation of the AbstractFFVSVertex class.
virtual Complex evaluate(Energy2 q2, const SpinorWaveFunction &sp1, const SpinorBarWaveFunction &sbar2, const VectorWaveFunction &vec3, const ScalarWaveFunction &sca4)=0
Members to calculate the helicity amplitude expressions for vertices and off-shell particles.
static void Init()
The standard Init function used to initialize the interfaces.
AbstractFFVSVertex & operator=(const AbstractFFVSVertex &)=delete
The assignment operator is private and must never be called.
AbstractFFVSVertex()
The default constructor.
The VertexBase class is the base class for all helicity amplitude vertices.
