The implementation of the process $\gamma\gamma \to ZZ$ at the one-loop level within {\tt SANC} system multi-channel approach is considered. The derived one-loop scalar form factors can be used for any cross channel after an appropriate permutation o

In this paper we present a description of the universal approach for analytic calculations for a certain class of $J$ functions for six topologies of the boxes for process $ud\rightarrow WA$. These functions $J$ arise at the reduction of infrared div

Modules and packages for the one-loop calculations at partonic level represent the first level of SANC output computer product. The next level represents Monte Carlo integrator mcsanc, realizing fully differential hadron level calculations (convoluti

It this paper we present the results obtained with the newly created Standard SANC modules for calculation of the NLO QCD corrections to single top production processes in s and t channels at the partonic level, as well as top-decays. The main aim of

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 regularisation of the top-legs associated infrared dive

In this paper we continue to study a special class of Passarino-Veltman functions J arising at the reduction of infrared divergent box diagrams. We describe a procedure of separation of two types of singularities, infrared and mass singularities, whi

In this paper we present the results of the implementation of the decay t -> b f1 f1 into the SANC system (f1 is a massless fermion). The new aspect of the work is the combination of QCD and EW corrections. All calculations are done at the one-loop l

We have calculated the electroweak radiative corrections at the O(alpha) level to the three channels of the process f_1 bar-f_1 Z A --> 0 and implemented them into the SANC system. Here A stands for the photon and f_1 for a first generation fermion w

In this paper we describe the implementation of the charged current decays of the kind t --> b l^+ nu_l (gamma) into framework of SANC system. All calculations are done taking into account one-loop electroweak correction in the Standard Model. The em

In this paper we describe the implementation of processes f_1 bar-f_1 ZZ --> 0 and f_1 bar-f_1 HZ --> 0 into the framework of SANC system. The f_1 stands for a massless fermion f whose mass is kept non-zero only in arguments of ln functions and --> 0
