Master integrals for e + e − → 2γ process at large energies and angles
Abstract We calculate master integrals for the two-loop QED corrections to e + e − → 2γ in terms of generalized power series with respect to electron mass. The coefficients of this series are expressed via Goncharov’s polylogarithms. Our approach exploits a number of modern multiloop methods: IBP re...
