The O ( α 2 ) initial state QED corrections to e + e − annihilation to a neutral vector boson revisited
/ Blümlein, J. ; De Freitas, A. ; Raab, C.G. ; Schönwald, K.
We calculate the nonsinglet, the pure singlet contribution, and their interference term, at O(α2) due to electronpair initial state radiation to e+e− annihilation into a neutral vector boson in a direct analytic computation without any approximation. [...]
