Marius Wiesemann, The LHC as a precision machine: Theory developments

Description
Measurements of electroweak interactions at the LHC require precision that can be reached only by state-of-the-art perturbative computations. In this talk, I will review a variety of QCD predictions focusing on vector-boson pair production processes. This involves NNLO QCD corrections which are now available for all diboson processes, transverse-momentum resummation of color singlets at NNLL, and the inclusion of NNLO QCD corrections in parton showers. I will also discuss important corrections beyond NNLO QCD, such as NLO EW corrections and NLO QCD corrections to the loop-induced gg contribution, which are necessary to reach the percent-level precision goal set by the LHC experiments.
