Massive two-loop QCD corrections to Diphoton Production at the LHC

Loops and Legs in Quantum Field Theory (LL), pp. 052

Abstract

In this talk, we present the current progress towards developing an automated framework to calculate the NNLO cross-section for the $q\bar{q} \to \gamma \gamma$ process including both light quark and massive top-quark contributions. The framework incorporates the virtual and the real-emission corrections in a local subtraction scheme for the phase-space integration.
