The AbstractVVVVVertex class is the base class for vector-vector-vector-vector interactions in ThePEG...
AbstractVVVVVertex & operator=(const AbstractVVVVVertex &)=delete
The assignment operator is private and must never be called.
virtual Complex evaluate(Energy2 q2, int iopt, const VectorWaveFunction &vec1, const VectorWaveFunction &vec2, const VectorWaveFunction &vec3, const VectorWaveFunction &vec4)=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.
The VertexBase class is the base class for all helicity amplitude vertices.
