Fermionic decay of charged Higgs boson in low-mass region in Georgi–Machacek model

Year: 2024

Type: article

Abstract: At the Large Hadron Collider (LHC), ATLAS and CMS collaborations observed various decay modes of the light charged Higgs bosons produced by top (anti)quark decays. In this paper, we are interested in the subsequent decay of the light charged Higgs boson into a charm and a strange quark-antiquark pair and into a tau and a tau-neutrino pair, separately, in the context of the Georgi-Machacek model, which offers a large triplet vacuum expectation value (vev) preserving custodial symmetry. We show that these experimental observations constrain the triplet vev from above. We explore the model parameter space consistent with the theoretical constraints, the latest Higgs data and the experimental data for light charged Higgs decaying to $cs$ and $\tau\nu_{\tau}$.
