Member Function Documentation

◆ clone()

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

Make a simple clone of this object.

Returns
a pointer to the new object.

Implements ThePEG::InterfacedBase.

◆ 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.

◆ 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.

Reimplemented from Herwig::DipoleSplittingReweight.

Definition at line 80 of file ColourMatrixElementCorrection.h.

◆ 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.

◆ operator=()

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

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

◆ persistentOutput()

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

Function used to write out object persistently.

Parameters
osthe persistent output stream written to.

Member Data Documentation

◆ 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.
