Lepton flavor conserving Z -> l^+ l^-$ decays in the general two Higgs doublet model

Abstract

We calculate the new physics effects to the branching ratios of the lepton flavor conserving decays Z -> l^+ l^- in the framework of the general two Higgs Doublet model. We predict the upper limits for the couplings |\barξ^{D}_{N,μτ}| and |\barξ^{D}_{N,ττ}| as 3\times 10^2 GeV and 1\times 10^2 GeV, respectively.
