Electron-positron annihilation to photons at O(α3) revisited
We apply the modern multiloop methods to the calculation of the total cross sections of electron-positron annihilation to 2 and 3 photons exactly in s/m2 with the accuracy O(α3). Examining the asymptotics of our results, we find agreement with Ref. [1] and discover mistakes in the results of Refs. [...
