摘要：

We discuss the leading logarithmic corrections of order alpha2 to Bhabha scattering cross section on the basis of order-alpha2 factorizable parts known at present. We implement these corrections in BHAGEN94, the new version of our event generator. We investigate the influence of these corrections and we estimate the size of smaller leftover corrections, which are still unknown. We conclude that they can give an error of 0.1% at small angle, but up to 1% at large angle.
