The high precision experimental results for the production of a pair of charged leptons or of a lepton-neutrino pair, the so called neutral- and charged-current Drell-Yan processes, allow precision tests of the electroweak Standard Model and the determination of fundamental parameters such as the W and Z boson masses and decay widths or the weak mixing angle.
I will illustrate recent results about the exact evaluation of the NNLO mixed QCD-EW corrections to both channels of the Drell-Yan processes, important in the studies at the gauge boson resonances, but also in the high-mass searches for New Physics.
