摘要：

A previous analysis of QED radiative corrections to Bhabha scattering in the vicinity of the Z0 is improved by a better analytical treatment of hard photon terms with sizeable effects on the tail of the resonance. A quantitative discussion of two-loop corrections and comparison with some existing Monte Carlo codes show that quite generally, the theoretical uncertainty at large angles cannot be reduced much below 1%.
