Abstract
Recent results for the asymptotic behavior of fermion scattering amplitudes in the Sudakov limit are discussed including next-to-leading logarithmic (NLL) and NNLL corrections. These are used for the analysis of the dominant electroweak corrections to the fermion-antifermion pair production in e + e − annihilation at high energy. The importance of angular dependent as well as subleading terms in emphasized.
