We study the QCD correction to the pair production of colored scalar particles in electron-position 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 differences from that for fermions.
