Abstract: (Elsevier)
We calculate the helicity amplitudes for the QED processes e + e − → γγγ , μ + μ − γ , and e + e − γ , in the limit of vanishing fermion masses. This is done by introducing explicit polarization vectors for the radiated photons. With the same technique, we also calculate these processes taking into account Z 0 exchange. Finally, we present the unpolarized cross sections in which mass terms are retained to describe the radiation of photons in directions parallel to those of the fermions.- QUANTUM ELECTRODYNAMICS
