Member Function Documentation

virtual double ThePEG::MEGG2GG::me2

(

)

const [virtual]

The matrix element for the kinematical configuration previously provided by the last call to setKinematics(), suitably scaled by sHat() to give a dimension-less number.

Returns:

the matrix element scaled with sHat() to give a dimensionless number.

Implements ThePEG::MEBase.

virtual Selector<const ColourLines *> ThePEG::MEGG2GG::colourGeometries

(

tcDiagPtr

diag

)

const [virtual]

Return a Selector with possible colour geometries for the selected diagram weighted by their relative probabilities.

Parameters:

diag

the diagram chosen.

Returns:

the possible colour geometries weighted by their relative probabilities.

Implements ThePEG::MEBase.

virtual Selector<DiagramIndex> ThePEG::MEGG2GG::diagrams

(

const DiagramVector &

dv

)

const [virtual]

Get diagram selector.

With the information previously supplied with the setKinematics method, a derived class may optionally override this method to weight the given diagrams with their (although certainly not physical) relative probabilities.

Parameters:

dv

the diagrams to be weighted.

Returns:

a Selector relating the given diagrams to their weights.

Reimplemented from ThePEG::MEBase.

virtual IBPtr ThePEG::MEGG2GG::clone

(

)

const [protected, virtual]

Make a simple clone of this object.

Returns:

a pointer to the new object.

Implements ThePEG::InterfacedBase.

virtual IBPtr ThePEG::MEGG2GG::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.
