Constraining SMEFT operators with associated $h\gamma$ production in Weak Boson Fusion

13 Mar 2020 Biekötter Anke Gomez-Ambrosio Raquel Gregg Parisa Krauss Frank Schönherr Marek

We consider the associated production of a Higgs boson and a photon in weak boson fusion in the Standard Model (SM) and the Standard Model Effective Theory (SMEFT), with the Higgs boson decaying to a pair of bottom quarks. Analysing events in a cut-based analysis and with multivariate techniques we determine the sensitivity of this process to the bottom-Yukawa coupling in the SM and to possible CP-violation mediated by dimension-6 operators in the SMEFT...
