Anomalous couplings in WZ production beyond NLO QCD — Francisco Campanario¹, •Robin Roth¹, Sebastian Sapeta², and Dieter Zeppenfeld¹ — ¹Institute for Theoretical Physics, KIT, Karlsruhe, Germany — ²CERN PH-TH, Geneva, Switzerland

We study WZ production with anomalous couplings (AC) at nNLO QCD using the LoopSim method in combination with the Monte Carlo program VBFNLO. Higher order corrections to WZ production are dominated by additional hard jet radiation. Those contributions are insensitive to AC and should thus be suppressed in analyses. We do this using a dynamical jet veto based on the transverse energy of the QCD and EW final state particles. This removes jet dominated events without introducing problematic logs like a fixed p_T jet veto.
