Comprehensive Analysis on Lepton Flavor Violating Higgs Boson to mu tau Decay in Supersymmetry without R Parity

Understand

In this paper we examine thoroughly the Higgs boson to mu tau 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.
