Two-loop Bhabha Scattering at High Energy beyond Leading Power Approximation

Abstract

We evaluate the two-loop $\mathcal{O}(m_e^2/s)$ 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.
