Electroweak bounds on Higgs pseudo-observables and $h \to 4 \ell$ decays

González-Alonso, Martín; Greljo, Admir; Isidori, Gino; Marzocca, David (2015). Electroweak bounds on Higgs pseudo-observables and $h \to 4 \ell$ decays. European Physical Journal C - Particles and Fields, 75(7):75:341.

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 $h\to 4\ell$ decay rates, dilepton spectra, and lepton-universality ratios are presented.
