Angular asymmetries as a probe for anomalous contributions to HZZ vertex at the LHC

Abstract

In this article, the prospects for studying the tensor structure of the HZZ vertex with the LHC experiments are presented. The structure of tensor couplings in Higgs di-boson decays is investigated by measuring the asymmetries and by studing the shapes of the final state angular distributions. The expected background contributions, detector resolution, and trigger and selection efficiencies are taken into account. The potential of the LHC experiments to discover sizeable non-Standard Model contributions to the HZZ vertex with $300{\mathrm{fb}}^{-1}$ and $3000{\mathrm{fb}}^{-1}$ is demonstrated.
