Abstract
We present our results for the one-loop contributions to the Higgs boson flavor-changing decays h → μτ in two extensions of the Standard Model: the Little Higgs Model with T-parity and the Two Higgs Doublet Model with a fourth generation of fermions. In both cases we find that the respective branching ratio BR(h → μτ) is of order 10−4 – 10−6. In the case of the 4G2HDM, the one-loop radiative correction is of the same order of magnitude as the tree level branching ratio. We find that in both models the branching ratios for the decay modes h → eτ, eμ are even more suppressed.
