virtual Complex ThePEG::Helicity::AbstractVVVVertex::evaluate	(	Energy2	q2,
		const VectorWaveFunction &	vec1,
		const VectorWaveFunction &	vec2,
		const VectorWaveFunction &	vec3
	)			[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.
	vec1	The wavefunction for the first vector.
	vec2	The wavefunction for the second vector.
	vec3	The wavefunction for the third vector.

Implemented in ThePEG::Helicity::VVVVertex.

		int	iopt,
		tcPDPtr	out,
		const VectorWaveFunction &	vec2,
		const VectorWaveFunction &	vec3,
		Energy	mass = -GeV,
		Energy	width = -GeV
	)			[pure virtual]

Evaluate the off-shell vector coming from the vertex.

Parameters:

	q2	The scale for the coupling at the vertex.
	iopt	Option of the shape of the Breit-Wigner for the off-shell vector.
	out	The ParticleData pointer for the off-shell vector.
	vec2	The wavefunction for the second vector.
	vec3	The wavefunction for the third vector.
	mass	The mass of the off-shell particle if not taken from the ParticleData object
	width	The width of the off-shell particle if not taken from the ParticleData object

Implemented in ThePEG::Helicity::VVVVertex.

static void ThePEG::Helicity::AbstractVVVVertex::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::VVVVertex.

AbstractVVVVertex& ThePEG::Helicity::AbstractVVVVertex::operator=

(

const AbstractVVVVertex &

)

[private]

The assignment operator is private and must never be called.

In fact, it should not even be implemented.
