| Abstract |
We study lepton flavor number violating rare B decays, b→slh± ll, in a seesaw model with low scale singlet Majorana neutrinos motivated by the resonant leptogenesis scenario. The branching ratios of inclusive decays b→slh±l?l with two almost degenerate singlet neutrinos at TeV scale are investigated in detail. We find that there exists a class of seesaw model in which the branching fractions of b→sτμ and τ→μγ can be as large as 10-10 and 10-9 within the reach of Super B factories, respectively, without being in conflict with neutrino mixings and mass-squared difference of neutrinos from neutrino data, invisible decay width of Z, and the present limit of Br(μ→eγ). In the model, the lepton number asymmetries are vanishing.
