Taking into account the constraints of the experimental data on the relevant free parameters, we calculate the branching ratios of the $LFV$ decay processes $\\tau^-\\to\\mu^- P_1 P_2 $ with $P_1 P_2$ = $\\pi^+\\pi^-$, $K^+K^-$ and $K^0\\bar{K^0}$ in the context of these two kinds of new physics models.
