Description
In the following years, the improvement of the high-energy measurements in particle accelerators will permit to obtain levels of accuracy never experienced before. In this scenario, the Drell-Yan process constitutes one of the main LHC processes that will benefit from the increase of the experimental dataset, with a future estimated precision of the order of 0,1% in the 1 TeV invariant mass region. Consequently, in order to perform a statistically significant comparison between theoretical predictions and experimental measurements, the inclusion of NNLO EW corrections in the cross section is required, whose evaluation represents the frontier from the computational point of view. In this talk, I will present our results for the evaluation of the virtual NNLO contributions to the Neutral Current Drell-Yan process, considering at this stage only the Feynman diagrams featuring an internal closed fermion loop. In particular, I will focus on the main aspects of our 2-loop EW renormalization program and the implementation of an automated procedure for the computation of the diagrams featuring first and second order counterterms.
