Two-loop QED/QCD corrections for polarized ${\hat{I}}^3{\hat{I}}^3\to {\hat{I}}^3{\hat{I}}^3$ process in SANCphot

Serge Bondarenko, Aidos Issadykov, Lidia Kalinovskaya +2

The new version of the SANCphot integrator has been prepared for fast and stable numerical calculations up to two loops for polarized light-by-light scattering. One-loop modules ba…
