Description
In this talk, I will present the recent calculation of the NNLO mixed QCD-electroweak corrections to the neutral-current Drell-Yan production of a pair of massless leptons within the nested soft-collinear subtraction framework. Thus, our computation is fully differential with respect to the final state particles.
Interestingly, the mixed corrections corrections are larger than what one would expect based on the magnitude of the coupling constants, and they
can exceed the pure NNLO QCD contribution in a large portion of the phase space.
At relatively low values of the dilepton invariant mass, around 200 GeV, we find unexpectedly large mixed QCD-electroweak corrections at the level of -1%.
At higher invariant masses, in the TeV region, we observe that these corrections can be well approximated by the product of QCD and electroweak corrections.
The plan of the talk is to first cover some technical aspects of the calculation, and then devote a discussion to results for fiducial cross sections and a selection of kinematic distributions.
