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

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 → 4 ℓ decay rates, dilepton spectra, and lepton-universality ra...

Description
Summary: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 → 4 ℓ decay rates, dilepton spectra, and lepton-universality ratios are presented.
