Heavy Quark Production at $e^{+}{e}^{-}$ Colliders in Multijet Events and a New Method of Computing Helicity Amplitudes

Abstract

Heavy quark production in multijet events at $e^{+}{e}^{-}$ colliders is studied at tree level. Total production rates are given and compared with the corresponding results for massless quarks. A new method of computing helicity amplitudes is briefly sketched. Talk presented at the XXIXth Rencontres de Moriond, QCD and High Energy Hadronic Interactions, Meribel, France, March 19-26 1994.
