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
InitExceptionif object could not be initialized properly.

Reimplemented from Herwig::MEPP2HiggsVBF.

◆ fullclone()

virtual IBPtr Herwig::MEPP2HiggsVBFPowheg::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 Herwig::MEPP2HiggsVBF.

◆ 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
ra 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.

◆ operator=()

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

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.

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

◆ persistentOutput()

void Herwig::MEPP2HiggsVBFPowheg::persistentOutput ( PersistentOStream os) const

Function used to write out object persistently.

Parameters
osthe persistent output stream written to.
