Detailed Description

The LPairAnalysis class is designed to analyse lepton pairs.

Therefore the lepton and antilepton with highest pt are selected from the event and some observables are computed and booked into histograms. The analysis is intended to anaylse top pair events where both W's are decaying semileptonically. Therefore, only the semileptonic top quark decay channels should be switched on. If no pair of (opposite sign) leptons is found in the final state a warning message is printed and nothing is booked. Output is created as topdrawer file

Member Function Documentation

◆ analyze()

virtual void Herwig::LPairAnalysis::analyze ( tEventPtr  event,
long  ieve,
int  loop,
int  state 
)
virtual

Analyze a given Event.

Note that a fully generated event may be presented several times, if it has been manipulated in between. The default version of this function will call transform to make a lorentz transformation of the whole event, then extract all final state particles and call analyze(tPVector) of this analysis object and those of all associated analysis objects. The default version will not, however, do anything on events which have not been fully generated, or have been manipulated in any way.

Parameters
eventpointer to the Event to be analyzed.
ievethe event number.
loopthe number of times this event has been presented. If negative the event is now fully generated.
statea number different from zero if the event has been manipulated in some way since it was last presented.

Reimplemented from ThePEG::AnalysisHandler.

◆ clone()

virtual IBPtr Herwig::LPairAnalysis::clone ( ) const
inlineprotectedvirtual

Make a simple clone of this object.

Returns
a pointer to the new object.

Reimplemented from ThePEG::AnalysisHandler.

Definition at line 79 of file LPairAnalysis.h.

◆ dofinish()

virtual void Herwig::LPairAnalysis::dofinish ( )
protectedvirtual

Finalize this object.

Called in the run phase just after a run has ended. Used eg. to write out statistics.

Reimplemented from ThePEG::InterfacedBase.

◆ fullclone()

virtual IBPtr Herwig::LPairAnalysis::fullclone ( ) const
inlineprotectedvirtual

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::AnalysisHandler.

Definition at line 85 of file LPairAnalysis.h.

◆ Init()

static void Herwig::LPairAnalysis::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=()

LPairAnalysis& Herwig::LPairAnalysis::operator= ( const LPairAnalysis )
privatedelete

The assignment operator is private and must never be called.

In fact, it should not even be implemented.
