The effects of non-universal extra dimensions on the \tau\to \mu   \bar{\nu_i} \nu_i decay
  We study \tau\to \mu \bar{\nu_i} \nu_i, i=e,\mu,\tau decays in the two Higgs doublet model, with the inclusion of one and two spatial non-universal extra dimensions. We observe that the branching ratio is sensitive to two extra dimensions in contrary to a single extra dimension.
