NLO QCD corrections to WH + jet production — Francisco Campanario², •Robin Roth¹, and Dieter Zeppenfeld¹ — ¹Institut für Theoretische Physik, Karlsruher Institut für Technologie, Karlsruhe, Deutschland — ²Theory Division, IFIC, University Valencia-CSIC, Valencia, Spain

WH production is one of the main production mechanisms of the Higgs boson and the only channel where a measurement of the Higgs decay to b quarks is feasible. Analyses in this channel study high-pt (boosted) Higgs bosons to suppress backgrounds. Additional jets contribute especially in the boosted phase space region and can be subject to large QCD corrections.

We present a fully differential calculation of WH + jet production at NLO QCD, which was implemented in the Monte Carlo program VBFNLO. Leptonic decays of the W and off-shell effects are included as well as top loop diagrams in the virtual contributions. The behavior of anomalous couplings is discussed.
