SUBROUTINE QIHPAR - Generate identity of current quark $q^{\prime\prime}$ and virtual quark $q^\prime$




In this routine the HERWIG [1] identities of the current quark $q^{\prime\prime}$ as well as of the virtual quark $q^\prime$ are generated. This proceeds as follows:

See Table 1 for a list of variables set in QIHPAR.
