Investigation of CP-Even Higgs Bosons Decays H *> *m*t Within Constraints of l&sub(a) *> l&sub(b)*g in a 3-3-1 Model with Inverse Seesaw Neutrinos / H.V.Quyet, T.T.Hieu, H.T.Hung, [et al.] // Chinese Journal of Physics [Electronic resource]. – 2024. – Vol. 90. – P. 166-186. – URL: https://doi.org/10.1016/j.cjph.2024.05.027. – Bibliogr.: 58.

In a 3-3-1 model with inverse seesaw neutrinos, we use a simple form of the Higgs potential to obtain four CP-even Higgs bosons (𝐻 ≡ ℎ*0&sub(1), ℎ*0&sub(2), ℎ*0&sub(3), ℎ*0 &sub(4)). We investigate H *> *m*t decays in the parameter space regions satisfying the experimental limits of l&sub(a) *> l&sub(b)*g with free parameters being the mass of the charged Higgs boson (𝑚&sub(𝐻&sup(* ()&sub(1)) and the mixing matrix of the heavy neutrinos (𝑀&sub(𝑅)). We show that there exist regions of parameter space where all partial widths 𝛤 (H *> *m*t) are less than the current experimental limit of (4.1 × 10*-*6 GeV). Analyzing the various contributing components to 𝛤 (H *> *m*t) , we also compare the mass of the SM-like Higgs boson with the corresponding ones with the other CP-even Higgs bosons in this model
