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=τ, l_j=μ) 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 $(1 0^{- 4} G e V), f or m_{H^{0}} = 150 G e V, an d t h e in t er m e d ia t e v a l u eso f t h eco u pl in g ξ ˉ_{N, τ μ}^{E} \sim 5 G e V (ξ ˉ_{N, τ τ}^{E} \sim 30 G e V) .
