- Аннотация: Radiative corrections to the single top s and t channel production processes are revisited. Complete one-loop electroweak corrections are calculated within the SANC system. New is a study of the regularization of the top-leg associated infrared divergences with aid of the complex mass of the top quark. A comparison of these electroweak corrections with those computed by the conventional method is presented both for top production and decays. Standard FORM and FORTRAN SANC modules are created. These modules are compiled into a package sanc_cc_v1.40, which may be downloaded from the SANC project home-pages. Many numerical results are presented at the partonic level with the aim to demonstrate the correct working of the modules. These modules are intended to be used in Monte Carlo generators for single top production at the LHC. Where possible, we compare our results with those existing in the literature; in particular, a comprehensive comparison with results of the CompHEP system is given.
