摘要：

We derive the coefficient of the O(alpha (2) log(s/m(e)(2))) fixed order contribution to elastic large-angle Bhabha scattering. We adapt the classification of infrared divergences, that was recently developed within dimensional regularization, and apply it to the regularization scheme with a massive photon and electron.
