Neutral Higgs H^0 \to h^0 (A^0) l_i^- l_j^+ decay

Abstract

We study the lepton flavor violating H^0 \to h^0 (A^0) l_i^- l_j^+ and the lepton flavor conserving H^0 \to h^0 (A^0) l_i^- l_i^+ (l_i=\tau, l_j=\mu) decays in the framework of the general two Higgs doublet model, the so-called model III. We estimate the decay width of LFV (LFC) process at the order of magnitude of 10^{-5} GeV$ (10^{-4} GeV), for m_{H^0}= 150 GeV, and the intermediate values of the coupling \bar{\xi}^{E}_{N,\tau \mu}\sim 5 GeV (\bar{\xi}^{E}_{N,\tau \tau}\sim 30 GeV). The experimental result of the process under consideration can ensure comprehensive information about the standard model Higgs boson $H^0$ and the model III free parameters.
