Testing CP-Invariance in Higgs VBF production with ATLAS using the Optimal Observable method and di-tau decays — •Coniavitis Elias, Schillo Christian, and Schumacher Markus — Albert-Ludwigs-Universität, Freiburg, Germany
CP-invariance in Higgs boson production via vector boson fusion is tested using the method of the optimal observable. In the present analysis the di-tau channel is utilised. A description of the method and analysis strategy is given, and the results of the ATLAS analysis using 20.3 fb−1 of proton-proton collision data at √s = 8 TeV are presented, along with a performance comparison to the signed Δφ variable previously proposed for this study.
