Analytic approach to the complete set of QED corrections to fermion pair production in e+ e- annihilation

We present the convolution integral for fermion pair production in the electroweak standard theory to order O(α) including also soft photon exponentiation. The result is complete in the sense that it includes initial- and final-state radiation and their interference. From the basic result — analytic formulae for the differential cross section — we also derive the corresponding expressions for the total cross section σT and the integrated forward-backward asymmetry AFB. The numerical importance of different contributions for the analysis of experiments at LEP/SLC energies is discussed.
