* 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
