Query: Second order contributions to elastic large-angle Bhabha scattering   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.
