Description
Quark-gluon strings are usually fragmented on the light cone in hadrons
(PITHIA, JETSET) or in small hadronic clusters which decay in hadrons
(HERWIG). In both cases the transverse momentum distribution is
parameterized as an unknown function. In CHIPS the colliding hadrons
stretch Pomeron ladders to each other and, when the Pomeron ladders meet
in the rapidity space, they create Quasmons (hadronic clusters bigger
then Amati-Veneziano clusters of HERWIG). The Quasmon size and the
corresponding transverse momentum distributions are tuned by the
Drell-Yan mu+mu- pairs. The final Quasmon fragmentation in CHIPS is
tuned by the e+e- and proton-antiproton annihilation, which is already
published.
