Member Function Documentation

◆ clone()

virtual IBPtr Herwig::MEPP2HiggsVBFPowheg::clone ( ) const

protectedvirtual

Make a simple clone of this object.

Returns: a pointer to the new object.

Reimplemented from Herwig::MEPP2HiggsVBF.

◆ doinit()

virtual void Herwig::MEPP2HiggsVBFPowheg::doinit ( )

protectedvirtual

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

Exceptions

InitException if object could not be initialized properly.

Reimplemented from Herwig::MEPP2HiggsVBF.

◆ dSigHatDR()

virtual CrossSection Herwig::MEPP2HiggsVBFPowheg::dSigHatDR ( ) const

virtual

Return the matrix element squared differential in the variables given by the last call to generateKinematics().

Reimplemented from Herwig::MEfftoffH.

◆ fullclone()

virtual IBPtr Herwig::MEPP2HiggsVBFPowheg::fullclone ( ) const

protectedvirtual

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

◆ generateKinematics()

virtual bool Herwig::MEPP2HiggsVBFPowheg::generateKinematics ( const double * r )

virtual

Generate internal degrees of freedom given nDim() uniform random numbers in the interval \( ]0,1[ \).

To help the phase space generator, the dSigHatDR should be a smooth function of these numbers, although this is not strictly necessary.

Parameters

r	a pointer to the first of nDim() consecutive random numbers.

Returns: true if the generation succeeded, otherwise false.

Reimplemented from Herwig::MEfftoffH.

◆ Init()

static void Herwig::MEPP2HiggsVBFPowheg::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.

◆ nDim()

virtual int Herwig::MEPP2HiggsVBFPowheg::nDim ( ) const

virtual

The number of internal degrees of freedom used in the matrix element.

Reimplemented from Herwig::MEfftoffH.

◆ operator=()

MEPP2HiggsVBFPowheg & Herwig::MEPP2HiggsVBFPowheg::operator= ( const MEPP2HiggsVBFPowheg & )

privatedelete

The assignment operator is private and must never be called.

In fact, it should not even be implemented.

◆ persistentInput()

void Herwig::MEPP2HiggsVBFPowheg::persistentInput	(	PersistentIStream &	is,
		int	version
	)

Function used to read in object persistently.
