◆ clone()

virtual IBPtr Herwig::ColourMatrixElementCorrection::clone ( ) const

protectedvirtual

Make a simple clone of this object.

virtual double Herwig::ColourMatrixElementCorrection::evaluate ( const DipoleSplittingInfo & s ) const

inlinevirtual

Return the reweighting factor for the given splitting type.

Implements Herwig::DipoleSplittingReweight.

◆ fullclone()

virtual IBPtr Herwig::ColourMatrixElementCorrection::fullclone ( ) const

protectedvirtual

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.

◆ hint()

virtual double Herwig::ColourMatrixElementCorrection::hint ( const DipoleSplittingInfo & s ) const

inlinevirtual

Return the absolute value of the colour matrix element correction as an enhancement hint for the sampling of the un-reweighted splitting kernel.

◆ hintOnly()

virtual bool Herwig::ColourMatrixElementCorrection::hintOnly ( const DipoleSplittingInfo & s ) const

inlinevirtual

Return true, if the reweight can be entirely absorbed into the hint.

A possible detuning will be switched off.

◆ Init()

static void Herwig::ColourMatrixElementCorrection::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.

◆ negativeScaling()

virtual void Herwig::ColourMatrixElementCorrection::negativeScaling ( const double c )

inlinevirtual

Set the factor in front of enhance used by the veto algorithm.

Reimplemented from Herwig::DipoleSplittingReweight.

◆ operator=()

ColourMatrixElementCorrection & Herwig::ColourMatrixElementCorrection::operator= ( const ColourMatrixElementCorrection & )

privatedelete

The assignment operator is private and must never be called.

In fact, it should not even be implemented.

◆ persistentInput()

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

Function used to write out object persistently.

Parameters

os	the persistent output stream written to.

◆ reweightFactor()

virtual void Herwig::ColourMatrixElementCorrection::reweightFactor ( const double c )

◆ lambda

double Herwig::ColourMatrixElementCorrection::lambda

private

Factor to shuffle the magnitude of the CMEC between the splitting kernel and the weight in the reweighted veto algorithm.

Referenced by hint(), and reweightFactor().

◆ negCMECScaling

double Herwig::ColourMatrixElementCorrection::negCMECScaling

private

Scaling factor multiplying all of the negative colour matrix element corrections.

The physically sensible value is 1.0, but this factor can be used to examine the effects of the negative contributions.
