Two-loop Bhabha scattering at high energy beyond leading power approximation
We evaluate the two-loop O(me2/s) contribution to the wide-angle high-energy electron–positron scattering in the double-logarithmic approximation. The origin and the general structure of the power-suppressed double logarithmic corrections are discussed in detail.
