static void Init()
The standard Init function used to initialize the interfaces.

Members to calculate the helicity amplitude expressions for vertices and off-shell particles.
AbstractVVVTVertex & operator=(const AbstractVVVTVertex &)=delete
The assignment operator is private and must never be called.
The VertexBase class is the base class for all helicity amplitude vertices.
