Higgs-Mediated $B_{s,d}^0\to \mu \tau ,e\tau$ and $\tau \to 3\mu ,e\mu \mu$ Decays in Supersymmetric Seesaw Models

Abstract

We study the rates allowed for the Higgs-mediated decays $B_{s,d}^0\to \mu \tau ,e\tau$ and $\tau \to \mu \mu \mu ,e\mu \mu$ in supersymmetric seesaw models, assuming that the only source of lepton flavour violation (LFV) is the renormalization of soft supersymmetry-breaking terms due to off-diagonal singlet-neutrino Yukawa interactions. These decays are strongly correlated with, and constrained by, the branching ratios for $B_{s,d}^0\to \mu \mu$ and $\tau \to \mu (e)\gamma .$ Parametrizing the singlet-neutrino Yukawa couplings $Y_{\nu }$ and masses $M_{N_i}$ in terms of low-energy neutrino data, and allowing the flavour-universal soft masses for sleptons and for squarks, as well as those for the two Higgs doublets, to be different at the unification scale, we scan systematically over the model parameter space. Neutrino data and the present experimental constraints set upper limits on the Higgs-mediated LFV decay rates $Br(B_{s}^0\toμτ, eτ)\lsim 4\times 10^{-9}$ and $Br(τ\toμμμ, eμμ)\lsim 4\times 10^{-10}$.
