Higgs to mu+tau Decay in Supersymmetry without R-parity    [PDF]

Abdessalem Arhrib, Yifan Cheng, Otto C. W. Kong
In this short letter, we report on lepton flavor violating Higgs decay into mu+tau under the scheme of a generic supersymmetric standard model without R-parity and list important combinations of R-parity violating parameters which can give significant branching ratios in experimental accessible region. We impose other known experimental constraints on the model parameters, considering both with and without a sub-eV neutrino masses bound on mass contributions from the R-parity violating parameters. In our analysis, the branching ratio of light Higgs to mu+tau can exceed 10^{-5} within admissible parameter space, while 10^{-2} is possible when the sub-eV neutrino masses bound is lifted.
