Precision physics and perturbative calculation

After successful runs at 7, 8 and 13 TeV and the discovery of the Higgs boson, there is still no clear evidence of BSM physics at the LHC. Although the high-luminosity phase will collect a large amount of data and exciting discoveries are still well
possible, it is by now clear that an alternative path to uncover possible new physics is the search for small deviations from the predictions of the Standard Model, and that precision is the key for this path. In this talk, we will discuss the challenges and
how we overcome them to obtain a per-mille level theoretical prediction in perturbation theory for Drell-Yan production, a precision benchmark process at the LHC. This prediction will have a direct impact on the precise measurement of the W-boson mass.
