  "abstract": "We study the lepton flavor violation (LFV) in tau decays in the framework of the supersymmetric seesaw mechanism with nonholomorphic terms for the lepton sector at a large $\\tan\\beta$. In particular, we analyze two new decay modes $\\tau\\to \\ell f_0(980)$ and $\\tau\\to \\ell K^{+} K^{-}$ arising from the scalar boson exchanges contrast to $\\tau\\to \\ell\\eta^{(\\prime)}$ from the pseudoscalar ones. We find that the decay branching ratios of the two new modes could be not only as large as the current upper limits of $O(10^{-7})$, but also larger than those of $\\tau\\to \\ell \\eta^{(\\prime)}$. Experimental searches for the two modes are important for the LFV induced by the scalar-mediated mechanism. In addition, we show that the decay branching ratios of $\\tau\\to \\ell \\mu^{+} \\mu^{-}$ are related to those of $\\tau\\to \\ell \\eta$ and $\\tau\\to \\ell f_0(980)$.",
