Implementation of SANC EW corrections in WINHAC Monte Carlo generator

In this paper we describe a check of the implementation of SANC system generated modules into the framework of WINHAC Monte Carlo event generator. At this stage of work we limit ourselves to inclusion of complete one-loop electroweak corrections. We perform a tuned comparison of the results derived with the aid of two codes: 1) the standard SANC integrator with a modified treatment of ISR QED corrections; 2) the modified WINHAC, upgraded with the SANC electroweak modules and downgraded to the O(alpha) QED corrections. The aim of this comparison is to prove the correctness of implementation of SANC EW modules into WINHAC. This is achieved through the presented tuned comparison.
