Constraining anomalous HVV interactions at proton and lepton colliders

Understand

In this paper, we study the extent to which CP parity of a Higgs boson, and more generally its anomalous couplings to gauge bosons, can be measured at the LHC and a future electron-positron collider.

• We consider several processes, including Higgs boson production in gluon and weak boson fusion and production of a Higgs boson in association with an electroweak gauge boson.
• We consider decays of a Higgs boson including $ZZ, WW, \gamma \gamma$, and $Z \gamma$.
• Matrix element approach to three production and decay topologies is developed and applied in the analysis.
