Mixed QCD-EW corrections to the Drell-Yan process

Abstract

Precise predictions of hard scattering processes at the LHC usually require the inclusion of NNLO corrections in QCD and NLO in EW. For some specific cases, this might not be sufficient to match the experimental accuracy, and higher-order radiative contributions must be taken into account too. In such situations, effects due the interplay among strong and electroweak interactions may be relevant. The Drell-Yan process provides a promiment example of ultra precision physics at the LHC. We recently completed the first calculation of the mixed QCD-EW corrections to the neutral current Drell-Yan process for massive leptons. In this proceeding, we elaborate on the comparison of the exact two-loop virtual amplitude with its approximation by a pole expansion and show phenomelogical results in the region of high invariant masses of the lepton pair system.
