Electroweak bounds on Higgs pseudo-observables and h → 4ℓ decays

Abstract

We analyze the bounds on the Higgs pseudo-observables following from electroweak constraints, under the assumption that the Higgs particle is the massive excitation of an SU(2) L doublet. Using such bounds, detailed predictions for h→4ℓ decay rates, dilepton spectra, and lepton-universality ratios are presented.
