*I* have no idea (without checking the montecarlorpp file)! Q-balls or 
R-hadrons, or something similarly wacky?

I stole (and then enhanced) the contents of that source file from the 
HepPID library, to avoid introducing a package dependence for a bunch of 
inline functions... so the logic within is not of our making.
