Detailed Description

This class corresponds to a kinematical cut to be made on a single outgoing parton from a hard sub-process.

There are four main virtual functions which must be overridden by concrete sub-classes. minKT() should return the minimum allowed transverse momentum of a given type, while minEta() and maxEta() should return the minimum and maximum allowed pseudo-rapidity for a particle of a given type as measured in the lab-system. Note that when applied in the rest frame of a hard sub-process, the transformation from the lab frame is assumed to be a simple boost along the z-axis. In addition the passCut() function should return true if a particle with a given type and given momentum will pass the cuts.
