Radiative corrections to e+e- → μ+μ- in the Glashow-Salam-Weinberg model

A complete renormalization scheme for the Glashow-Salam-Weinberg model is presented. The full one-loop weak radiative corrections to the longitudinal polarization asymmetry, Asub(pol), and the forward-backward asymmetry, Asub(fb), in e+e- → μ+ μ- are calculated both on and off resonance. On resonance the results depend extremely sensitively on the Z0 mass, Msub(Z), and to a lesser extent on the top quark mass, msub(t), and the Higgs mass, Msub(H). The results are displayed over the full range of the parameters allowed by experimental and theoretical constraints. Comparison is made with other calculations of Asub(fb) and the agreement is found to be good. The predictions are also compared with measurements of Asub(fb) off resonance and are found in all cases to lie within the experimental errors. (author)
