Detailed Description

The PartonBin class is used by the PartonExtractor class to store information about the extraction of a parton from a particle.

Several PartonBin objects can be used to specify a whole chain of partons extracted from particles extracted from other particles. A PartonBin without an incoming() PartonBin represents the incoming particle itself and is used to stop recursion.

After the extraction of a parton, the kinematical variables of that extraction is stored in a orresponding PartonBinInfo object.

Member Function Documentation

nDim()

int ThePEG::PartonBin::nDim

(

bool

doscale

)

Detemine the number of degrees of freedom needed to generate the phase space of this and parent partons.

If doscale is true this bin is expected to generate the scale in addition to the momentum fraction.
