Properties of hadron distributions in reactions containing very heavy quarks
Abstract
We study, in the framework of the naive quark-parton model, production and decay dynamics for processes containing a very heavy quark Q of a new flavor, decaying via weak interactions. We argue the following. (i) The event-by-event distribution of hadrons is similar to what would exist in a similar direct process involving the same produced partons (with the same momenta), but not involving a cascade decay. (ii) For neutrino production, electroproduction, and e+e- annihilation, at energies far above threshold, the inclusive momentum distribution of a stable hadron H containing the Q peaks near the maximum momentum, i.e., at values of the scaling variable z~1. (iii) For events containing a nonleptonic decay of Q into ordinary quarks via Q-->qq¯q, the leading hadron distribution is characterized by multiplicity ~3 times normal multiplicity, as well as abanormally large transverse momenta.
