Hard gluon emission from colored scalar pairs\break in e^+ e^- annihilation

Abstract

We study QCD correction to the pair production of colored scalar particles in electron-positron annihilation with an emphasis on gluon emission in the final state. We discuss the usefulness of working in a ``quasi-two-body'' frame and present the helicity amplitudes for the process. We compare the final state configuration with fermion pair production and find that the three-jet fraction for the scalars shows quantitative difference from that for fermions.
