protectedvirtual |
Make a clone of this object, possibly modifying the cloned object to make it sane.
Reimplemented from ThePEG::InterfacedBase.
|
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.
Reimplemented from ThePEG::TwoCutBase.
Return the minimum allowed value of the Durham

Implements ThePEG::TwoCutBase.
Return the minimum allowed value of the longitudinally invariant
-algorithms distance measure.
This is defined as for two outgoing partons, or simply
or
for a single outgoing parton. Returns 0 if both partons are incoming. A null pointer indicates an incoming parton, hence the type of the incoming parton is irrelevant.
Implements ThePEG::TwoCutBase.
|
private |
The assignment operator is private and must never be called.
In fact, it should not even be implemented.
|
virtual |
Return true if a pair of particles with type pitype and pjtype and momenta pi and pj respectively passes the cuts.
inci and inj indicates if the corresponding particles are incoming.
Reimplemented from ThePEG::TwoCutBase.

int | version | ||

Function used to read in object persistently.
is | the persistent input stream read from. |
version | the version number of the object when written. |
Reimplemented from ThePEG::Interfaced.
void ThePEG::MadGraphTwoCut::persistentOutput | ( | PersistentOStream & | os | ) | const |
Function used to write out object persistently.
os | the persistent output stream written to. |
Reimplemented from ThePEG::Interfaced.
