Özet

We study tau --> munu(i)nu(i), i = e, mu, tau decay in the model III version of the two Higgs doublet model. We calculated the BR at the order of magnitude 10(-6)-10(-4) for intermediate values of the Yukawa couplings. Furthermore, we predict the upper limit of the coupling for the tau-h(0)(A(0))-tau transition as similar to0.3 in the case that the BR is similar to10(-6). We observe that the experimental result of the process under consideration can give comprehensive information about the physics beyond the standard model and the free parameters existing.
