Abstract

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 into account. The corresponding package for numeric calculations is presented. For checking of the results’ correctness we make a comparison with the other independent calculations.
