About implementation of e+e−→ff̄ processes into the framework of SANC system

This report gives a description of how the automatic calculations of the differential cross-sections of the processes e+e−→ff̄ (with an arbitrary final-state massive fermion) at one-loop level can be realized within the SANC system (Nucl. Instr. and meth., these proceedings). The results of numerical comparison with other calculations are presented.
