Detailed Description

The AnomalousWWHVertex class implements the option of an anomalous coupling in the $h^0W^+W^+$ and $h^0Z^0Z^0$ vertices.

The options of using either the exact Standard Model, a CP-odd

\[\frac1{\Lambda}J_1^\mu J_2^\nu\epsilon^{\mu\nu\alpha\beta}q_{1\alpha}q_{2\beta},\]

or CP-even

\[\frac1{\Lambda}J_1^\mu J_2^\nu \left[g_{\mu\nu}q_1 \cdot q_2-q_{1\nu}q_{2\mu}\right],\]

form, where $\Lambda$ is the scale of the new operator.

Member Function Documentation

virtual IBPtr Herwig::AnomalousWWHVertex::clone ( ) const [protected, virtual]

Make a simple clone of this object.

Returns:
a pointer to the new object.

Implements ThePEG::InterfacedBase.

virtual void Herwig::AnomalousWWHVertex::doinit ( ) [protected, virtual]

Initialize this object after the setup phase before saving and EventGenerator to disk.

Exceptions:
InitExceptionif object could not be initialized properly.

Reimplemented from ThePEG::Helicity::VertexBase.

virtual IBPtr Herwig::AnomalousWWHVertex::fullclone ( ) const [protected, virtual]

Make a clone of this object, possibly modifying the cloned object to make it sane.

Returns:
a pointer to the new object.

Reimplemented from ThePEG::InterfacedBase.

static void Herwig::AnomalousWWHVertex::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::GeneralVVSVertex.

AnomalousWWHVertex& Herwig::AnomalousWWHVertex::operator= ( const AnomalousWWHVertex ) [private]

The assignment operator is private and must never be called.

In fact, it should not even be implemented.

Function used to read in object persistently.

Parameters:
isthe persistent input stream read from.
versionthe version number of the object when written.

Reimplemented from ThePEG::Helicity::VertexBase.

Function used to write out object persistently.

Parameters:
osthe persistent output stream written to.

Reimplemented from ThePEG::Helicity::VertexBase.

virtual void Herwig::AnomalousWWHVertex::setCoupling ( Energy2  q2,
tcPDPtr  part1,
tcPDPtr  part2,
tcPDPtr  part3 
) [virtual]

Calculate coupling.

Parameters:
q2Scale at which to evaluate couplings
part1ParticleDataPointer to first particle
part2ParticleDataPointer to second particle
part3ParticleDataPointer to third particle

Implements ThePEG::Helicity::GeneralVVSVertex.
