The static object used to initialize the description of this class. |
This is the implementation of the matrix element for the process vector-vector to scalar-scalar.
It inherits from GeneralHardME and implements the required virtual functions.
virtual IBPtr Herwig::MEvv2ss::clone | ( | ) | const [inline, protected, virtual] |
Make a simple clone of this object.
Implements ThePEG::InterfacedBase.
virtual void Herwig::MEvv2ss::constructVertex | ( | tSubProPtr | sub | ) | [virtual] |
virtual void Herwig::MEvv2ss::debug | ( | double | me2 | ) | const [protected, virtual] |
A debugging function to test the value of me2 against an analytic function.
me2 | The value of the ![]() |
Reimplemented from Herwig::GeneralHardME.
virtual void Herwig::MEvv2ss::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::MEvv2ss::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::MEvv2ss::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::MEvv2ss::me2 | ( | ) | const [virtual] |
The matrix element for the kinematical configuration previously provided by the last call to setKinematics(), suitably scaled by sHat() to give a dimension-less number.
Implements Herwig::GeneralHardME.
The assignment operator is private and must never be called.
In fact, it should not even be implemented.

is | the persistent input stream read from. |
version | the version number of the object when written. |
Reimplemented from Herwig::GeneralHardME.
void Herwig::MEvv2ss::persistentOutput | ( | PersistentOStream & | os | ) | const |
Function used to write out object persistently.
os | the persistent output stream written to. |
Reimplemented from Herwig::GeneralHardME.
