virtual Complex ThePEG::Helicity::AbstractSSTVertex::evaluate ( Energy2  q2,
const ScalarWaveFunction sca1,
const ScalarWaveFunction sca2,
const TensorWaveFunction ten3 
) [pure virtual]

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

Evalulate the vertex.

Parameters:
q2 The scale $q^2$ for the coupling at the vertex.
sca1 The wavefunction for the first scalar.
sca2 The wavefunction for the second scalar
ten3 The wavefunction for the tensor.

Implemented in ThePEG::Helicity::SSTVertex.

int  iopt,
tcPDPtr  out,
const ScalarWaveFunction sca1,
const TensorWaveFunction ten3,
Energy  mass = -GeV,
Energy  width = -GeV 
) [pure virtual]

Evaluate the off-shell scalar coming from the vertex.

Parameters:
q2 The scale $q^2$ for the coupling at the vertex.
iopt Option of the shape of the Breit-Wigner for the off-shell scalar.
out The ParticleData pointer for the off-shell scalar.
sca1 The wavefunction for the first scalar.

int  iopt,
tcPDPtr  out,
const ScalarWaveFunction sca1,
const ScalarWaveFunction sca2,
Energy  mass = -GeV,
Energy  width = -GeV 
) [pure virtual]

Evaluate the off-shell tensor coming from the vertex.

Parameters:
q2 The scale $q^2$ for the coupling at the vertex.
iopt Option of the shape of the Breit-Wigner for the off-shell tensor.
out The ParticleData pointer for the off-shell tensor.
sca1 The wavefunction for the first scalar.

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::SSTVertex.

static void ThePEG::Helicity::AbstractSSTVertex::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::SSTVertex.

AbstractSSTVertex& ThePEG::Helicity::AbstractSSTVertex::operator= ( const AbstractSSTVertex  )  [private]

The assignment operator is private and must never be called.

In fact, it should not even be implemented.
