Comprehensive analysis on lepton flavor violating Higgs boson to μ∓τ± decay in supersymmetry without R parity
Abstract
In this paper we examine thoroughly the Higgs boson to μ∓τ± decay via processes involving R parity violating couplings. By means of full one-loop diagrammatic calculations, we found that even if known experimental constraints, particularly including the stringent sub-eV neutrino mass bounds, give strong restrictions on some of the R parity violating parameters, the branching ratio could still achieve notable value in the admissible parameter space. Hence, the flavor violating leptonic decay is of interest to future experiments. We present here key results of our analysis. Based on the analysis, we give some comments on h0→e∓μ± and h0→e∓τ± also.
