The angular distribution and the s dependence of the total cross section for the process e+e- → μ+μ- have been measured using the JADE detector at PETRA. After radiative corrections, a forward-backward asymmetry of -(11.8±3.8) % was observed at an average centre of mass energy of 33.5 GeV. For comparison, an asymmetry of -7.8 % is expected on the basis of the standard Glashow-Salam-Weinberg model.
