NAME

subroutine GetLeading_PY

PURPOSE

Try to reconstruct for every outgoing partice of a Jetset fragmentation the number of leading quarks of this particle. i.e. the number of quarks contained in the final partickle, which already spanned the fragmented string.

INPUTS

The Pythia common blocks have to be set (no PYEDIT!)

OUTPUT

in common block /PYJETS/:

  • K(i,4): 0,1,2,3 according number of leading quarks
  • K(i,5): number of fragmented string in this event
