The AbstractFFVVVertex class provides a base class for all fermion-fermion-vector-vector vertices in ...
AbstractFFVVVertex & operator=(const AbstractFFVVVertex &)=delete
The assignment operator is private and must never be called.
virtual Complex evaluate(Energy2 q2, const SpinorWaveFunction &sp1, const SpinorBarWaveFunction &sbar2, 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.
