Two-loop form factors for diphoton production in quark annihilation channel with heavy quark mass dependence

Abstract We present the computation of the two-loop form factors for diphoton production in the quark annihilation channel. These quantities are relevant for the NNLO QCD corrections to diphoton production at LHC recently presented in [1]. The computation is performed retaining full dependence on th...
