Make a clone of this object, possibly modifying the cloned object to make it sane.
Reimplemented from ThePEG::MEee2gZ2qq.
|
virtual |
Generate internal degrees of freedom given nDim() uniform random numbers in the interval \( ]0,1[ \).
To help the phase space generator, the dSigHatDR should be a smooth function of these numbers, although this is not strictly necessary.
r | a pointer to the first of nDim() consecutive random numbers. |
Reimplemented from ThePEG::ME2to2Base.
|
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.
