Abstract
Constraints on anomalous HVV couplings are placed using events from the Run 1 or Run 2 data taking periods. The general formalism of these couplings was already mentioned in detail in Sect. 3.1. In the Run 1 analysis, the tested contributions are a 2, a 3, Λ1 for the HZZ vertex, a2Zγ, a3Zγ, and Λ1Zγ for the HZγ vertex, and a2γγ and a3γγ for the Hγγ vertex. HZZ and HWW couplings are assumed to be the same, but test of separating them on the decay side are also performed via comparison to events from H →WW → 2ℓ2ν events. In Run 2, only the anomalous HZZ contributions, or the Λ1Zγ contribution, are tested from the 4ℓ decay with the assumption that HZZ and HWW couplings are the same.
