Definition at line 99 of file MEHiggsPairOL.h.

◆ orderInAlphaS()

virtual unsigned int Herwig::MEHiggsPairOL::orderInAlphaS ( ) const

inlinevirtual

Return the order in \(\alpha_S\) in which this matrix element is given.

Implements ThePEG::MEBase.

Definition at line 93 of file MEHiggsPairOL.h.

◆ persistentInput()

void Herwig::MEHiggsPairOL::persistentInput	(	PersistentIStream &	is,
		int	version
	)

Function used to read in object persistently.

Parameters

is	the persistent input stream read from.
version	the version number of the object when written.

◆ persistentOutput()

void Herwig::MEHiggsPairOL::persistentOutput ( PersistentOStream & os ) const

Function used to write out object persistently.

Parameters

os	the persistent output stream written to.

◆ rebind()

virtual void Herwig::MEHiggsPairOL::rebind ( const TranslationMap & trans )

protectedvirtual

Rebind pointer to other Interfaced objects.

Called in the setup phase after all objects used in an EventGenerator has been cloned so that the pointers will refer to the cloned objects afterwards.

Parameters

trans a TranslationMap relating the original objects to their respective clones.

Exceptions

RebindException if no cloned object was found for a given pointer.

Reimplemented from ThePEG::InterfacedBase.

◆ scale()

virtual Energy2 Herwig::MEHiggsPairOL::scale ( ) const

virtual

Return the scale associated with the last set phase space point.

Implements ThePEG::MEBase.

◆ setKinematics()

virtual void Herwig::MEHiggsPairOL::setKinematics ( )

virtual

Set the typed and momenta of the incoming and outgoing partons to be used in subsequent calls to me() and colourGeometries() according to the associated XComb object.

Reimplemented from Herwig::HwMEBase.
