摘要：

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(1)(0), h(2)(0), h(3)(0), h(4)(0)). We investigate H -> mu tau decays in the parameter space regions satisfying the experimental limits of l(a) -> l(b)gamma with free parameters being the mass of the charged Higgs boson (mH(1 +/-)) and the mixing matrix of the heavy neutrinos (M-R). We show that there exist regions of parameter space where all partial widths Gamma(H -> mu tau) are less than the current experimental limit of (4.1 x 10(-6) GeV). Analyzing the various contributing components to Gamma(H -> mu tau), 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.
