Herwig::MEMatching
MEMatching implements NLO matching with matrix element correction (aka Powheg).
Definition:
MEMatching.h:28
Herwig::MEMatching::needsSplittingGenerator
virtual bool needsSplittingGenerator() const
Return true, if this shower approximation will require a splitting generator.
Definition:
MEMatching.h:43
Herwig::MEMatching::operator=
MEMatching & operator=(const MEMatching &)=delete
The assignment operator is private and must never be called.
Herwig::MEMatching::MEMatching
MEMatching()
The default constructor.
Herwig::MEMatching::persistentOutput
void persistentOutput(PersistentOStream &os) const
Function used to write out object persistently.
Herwig::MEMatching::me2
virtual double me2() const
Return the shower approximation splitting kernel for the given pair of Born and real emission configu...
Herwig::MEMatching::Init
static void Init()
The standard Init function used to initialize the interfaces.
Herwig::MEMatching::persistentInput
void persistentInput(PersistentIStream &is, int version)
Function used to read in object persistently.
Herwig::MEMatching::needsTruncatedShower
virtual bool needsTruncatedShower() const
Return true, if this shower approximation will require a truncated parton shower.
Definition:
MEMatching.h:55
Herwig::MEMatching::hasHEvents
virtual bool hasHEvents() const
Return true, if this shower approximation will require H events.
Definition:
MEMatching.h:49
Herwig::MEMatching::theTruncatedShower
bool theTruncatedShower
True, if a truncated parton shower should be generated.
Definition:
MEMatching.h:133
Herwig::MEMatching::clone
virtual IBPtr clone() const
Make a simple clone of this object.
Herwig::MEMatching::dSigHatDR
virtual CrossSection dSigHatDR() const
Return the shower approximation to the real emission cross section for the given pair of Born and rea...
Herwig::MEMatching::fullclone
virtual IBPtr fullclone() const
Make a clone of this object, possibly modifying the cloned object to make it sane.
Herwig::ShowerApproximation
ShowerApproximation describes the shower emission to be used in NLO matching.
Definition:
ShowerApproximation.h:35
Herwig::ShowerApproximation::restrictPhasespace
bool restrictPhasespace() const
Return true, if the phase space restrictions of the dipole shower should be applied.
Definition:
ShowerApproximation.h:315
Herwig::ShowerApproximation::profileScales
Ptr< HardScaleProfile >::tptr profileScales() const
Return profile scales.
