Precise QCD predictions for the LHC — •Alexander Huss — Theoretical Physics Department, CERN, 1211 Geneva 23, Switzerland

The LHC offers the widest range of physics opportunities: Among the highest priorities is the understanding of the Higgs boson and the search for physics beyond the SM. In view of the absence of striking new-physics signals to date, BSM physics is likely hiding in small and subtle effects. Revealing such phenomena though precision studies critically relies on our ability to predict both signal and background processes with high precision.

I will review some state-of-the art QCD predictions for hadron colliders and their impact on the interpretation of LHC measurements. A focus will be put on perturbative calculations for Higgs- and gauge-boson processes and the underlying subtraction procedures. Current limitations will be addressed with an outlook on future developments relevant for precision phenomenology.
