Abstract: (Elsevier)

The complete α 3 -contribution to the angular asymmetry in the differential cross section for e + e − → μ + μ − is calculated, including hard photon emission. The results are of interest for e + e − colliding beam experiments in which the charges of the outgoing muons are detected. Numerical results are given for the case of experiments with small energy resolutions.
