Precision Description of Processes at Colliders in the SANC System
A review of the SANC computer system intended for theoretical support of experiments at colliders is presented. The system allows the precision predictions to be obtained semiautomatically for a wide class of ...

J functions for the process ud→WA
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 the process ud → WA. These functions J arise at th...

Zγγγ → 0 Processes in SANC
We describe the analytic and numerical evaluation of the γγ → γZ process cross section and the Z → γγγ decay rate within the SANC system multi-channel approach at the one-loop accuracy level with all masses taken...

Standard model light-by-light scattering in SANC: Analytic and numeric evaluation
The implementation of the Standard Model process γγ → γγ through a fermion and boson loop into the framework of SANC system and additional precomputation modules used for calculation of massive box diagrams are d...
