static ClassDescription< MEff2sv > | initMEff2sv |
The static object used to initialize the description of this class. |
The MEff2sv class is designed to implement the matrix element for a fermion-antifermion to vector-scalar hard process.
It inherits from GeneralHardME and implements the appropriate virtual functions for this specific spin combination.
virtual IBPtr Herwig::MEff2sv::clone | ( | ) | const [inline, protected, virtual] |
Make a simple clone of this object.
Implements ThePEG::InterfacedBase.
virtual void Herwig::MEff2sv::constructVertex | ( | tSubProPtr | sub | ) | [virtual] |
Construct the vertex information for the spin correlations.
sub | Pointer to the relevent SubProcess |
Reimplemented from ThePEG::MEBase.
virtual void Herwig::MEff2sv::doinit | ( | ) | [protected, virtual] |
Initialize this object after the setup phase before saving an EventGenerator to disk.
InitException | if object could not be initialized properly. |
Reimplemented from ThePEG::InterfacedBase.

virtual IBPtr Herwig::MEff2sv::fullclone | ( | ) | const [inline, protected, virtual] |
Make a clone of this object, possibly modifying the cloned object to make it sane.
Reimplemented from ThePEG::InterfacedBase.
static void Herwig::MEff2sv::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.
Reimplemented from Herwig::GeneralHardME.
virtual double Herwig::MEff2sv::me2 | ( | ) | const [virtual] |

Implements Herwig::GeneralHardME.
The assignment operator is private and must never be called.
In fact, it should not even be implemented.

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. |
