On the threshold behaviour of heavy top production
(1990) In Zeitschrift für Physik C Particles and Fields 48(4). p.613-621- Abstract
If the top is heavy, as now seems likely, the {Mathematical expression} threshold behaviour is given by perturbative QCD. The QCD threshold interaction can be formulated in terms of a potential, attractive or repulsive depending on whether the {Mathematical expression} is in a colour singlet or octet state. This gives a suppression factor for octet production. Singlet production is enhanced, both above threshold and, by resonance formation, below it. While e+e- annihilation only proceeds in the singlet {Mathematical expression} channel, hadronhadron collisions contain a non-trivial mixture of the two. In this paper we review the relevant threshold factor formulae, and present phenomenological consequences for... (More)
