Constraints on anomalous $HVV$ couplings of the Higgs boson in proton collisions at $7$ and $8\mathrm{TeV}$
ORAL
Abstract
Under the hypothesis that the resonance is a spin-zero boson, the tensor structure of the interactions of the recently discovered Higgs boson is performed using the $H \to ZZ,Z\gamma^*,\gamma^*\gamma^*\to 4\ell$ and $H \to WW \to \ell\nu\ell\nu$ decay modes. The full dataset recorded by the CMS experiment during the LHC Run 1 is used, corresponding to an integrated luminosity of up to $5.1\mathrm{fb}^{-1}$ at a center-of-mass energy of $7\mathrm{TeV}$ and up to $19.7\mathrm{fb}^{-1}$ at $8\mathrm{TeV}$. Limits on eleven anomalous contributions are set. Tighter constraints on anomalous $HVV$ interactions are obtained by combining the $HZZ$ and $HWW$ measurements. All observations are consistent with the expectations for the standard model Higgs boson with the quantum numbers $J^{PC}=0^{++}$.
