NLO QCD corrections to tri-boson production in hadronic collisions

ulti-lepton signatures appear in many new physics searches at the CERN Large Hadron Collider LHC. In this thesis, WWZ as well as ZZW production with subsequent leptonic decay of the three vector bosons is considered as a Standard Model source of multi-lepton events. The next-to-leading order QCD corrections for the full pp -> 6 lepton production cross sections in hadronic collisions have been computed. Results are implemented in a fully flexible parton-level Monte Carlo program, VBFNLO.
