摘要：

The cross section of hard pair production in large-angle Bhabha scattering is calculated in the leading and next-to-leading logarithmic approximations. Eight regions of the collinear kinematics, when the final particles imitate a process of the 2 --> 2 type, and three semicollinear regions, when the final particles imitate a process of the 2 --> 3 type, are considered. Analytical formulae for differential cross sections are presented.
