NAME

subroutine PerformAddDecay(PartVec,time)

PURPOSE

Loop over the whole particle vector and perform some (additional) decays, as e.g. kaon to pions. This is intended to be used with some "reconstruction" routines as used by experimentalists.

Here we use the JETSET part of PYTHIA, which is totally independend of any fragmentation stuff etc. This means for particles decaying by this routine, branching ratios and angular distributions are as given by PYTHIA parameters, cf. "PYLIST12.txt".

please note: we use PYTHIA, i.e. PYTHIAv6.2

NOTES

At the moment we are just decaying kaon and kaonBar (ID=110,111). It can be easily expanded to all other particles, if one sets the corresponding "stability flag" in array MDCY correctly.
