Abstract
The cross section for gluon bremsstrahlung, e+e− → qqg, is calculated for the case of arbitrarily polarized electron-position beams, including weak interaction effects, in the Glashow-Weinberg-Salam model. The weak neutral current effects somewhat reduce the dependence of the cross section on transverse beam polarization, and lead to a rotation of the azimuthal distributions, as compared with the low-energy limit. This leads to flavour separation, in the sense that the azimuthal distributions are different for up and down quark flavours.
