Constraints on Anomalous HWW Interactions using Higgs boson decays to W+W- in the fully leptonic final state

Studies on anomalous Higgs boson interactions with pairs of W gauge bosons, as well as its spin parity are presented. The analysis is performed in the Higgs boson decay channel to W$^+$W$^-$ with two charged leptons, one electron and one muon, and two neutrinos in the final state. The analysis is based on data recorded with the CMS detector in pp collisions at a center of mass energy of 8~TeV at the LHC. The tensor structure of interactions under the spin-0 hypothesis is examined and alternative spin-parity hypotheses are studied to cover the spin-1 and spin-2 models. The hypothesis of the standard model Higgs boson for quantum numbers and couplings is consistent with the data and the results are expressed as exclusion bounds of several spin-parity hypotheses and anomalous coupling parameters.
