Seminarium Teorii Oddziaływań Elementarnych

In this talk I will discuss the charged-current Drell-Yan (DY) process, i.e. single W-boson production with leptonic decay in hadron collisions, and its role in the Standard Model precision tests as well as searches for the Higgs boson and for "new physics". I will show important differences between the Tevatron and the LHC with respect to DY processes and discuss their consequences for the W mass measurement. Finally, I will briefly present the Monte Carlo event generator WINHAC, dedicated to precision predictions for the above processes at the LHC.
