H^+ -> W^+ l_i^- l_j^+$ decay in the two Higgs doublet model
Abstract
We study the lepton flavor violating H^+ -> W^+ l_i^- l_j^+ and the lepton flavor conserving $H^+ -> W^+ l_i^- l_i^+ (l_i=τ, l_j=μ) decays in the general 2HDM, so called model III. We estimate the decay width Γfor LFV (LFC) at the order of the magnitude of (10^{-11}-10^{-5}) GeV ((10^{-9}-10^{-4}) GeV), for 200 GeV\leq m_{H^\pm}\leq 400 GeV, and the intermediate values of the coupling \barξ^{E}_{N,τμ}\sim 5 GeV (\barξ^{E}_{N,τ τ}\sim 30 GeV). We observe that the experimental result of the process under consideration can give comprehensive information about the physics beyond the standard model and the existing free parameters.
