virtual Complex ThePEG::Helicity::AbstractVVVVVertex::evaluate	(	Energy2	q2,
		int	iopt,
		const VectorWaveFunction &	vec1,
		const VectorWaveFunction &	vec2,
		const VectorWaveFunction &	vec3,
		const VectorWaveFunction &	vec4
	)			[pure virtual]

Members to calculate the helicity amplitude expressions for vertices and off-shell particles.

Evaluate the vertex.

Parameters:

	q2	The scale for the coupling at the vertex.
	iopt	Evaluation option, 0 just evaluate the four point vertex, 1 include all the three point diagrams as well.
	vec1	The wavefunction for the first vector.
	vec2	The wavefunction for the second vector.
	vec3	The wavefunction for the third vector.
	vec4	The wavefunction for the fourth vector.

Implemented in ThePEG::Helicity::VVVVVertex.

static void ThePEG::Helicity::AbstractVVVVVertex::Init

(

)

[static]

The standard Init function used to initialize the interfaces.

Called exactly once for each class by the class description system before the main function starts or when this class is dynamically loaded.

Reimplemented from ThePEG::Helicity::VertexBase.

Reimplemented in ThePEG::Helicity::VVVVVertex.

AbstractVVVVVertex& ThePEG::Helicity::AbstractVVVVVertex::operator=

(

const AbstractVVVVVertex &

)

[private]

The assignment operator is private and must never be called.

In fact, it should not even be implemented.
