Electroweak Effects in Neutral Current Drell-Yan Processes within SANC System

Abstract

The complete one-loop electroweak radiative corrections to the neutral current Drell-Yan process $pp\to {\ell }^{+}{\ell }^{-}X$ are presented for the case of longitudinal polarization of initial particles. The calculations are based on the SANC computer system. The paper contains a brief description of the SANC approach and a discussion of the sources of theoretical uncertainties in electroweak effects.
