Lepton-flavor violation via right-handed neutrino Yukawa couplings in the supersymmetric standard model

Lepton-flavor violation via right-handed neutrino Yukawa couplings in the supersymmetric standard model

Various lepton-flavor violating (LFV) processes in the supersymmetric standard model with right-handed neutrino supermultiplets are investigated in detail. It is shown that large LFV rates are obtained when $\tan \beta $ is large. In the case where the mixing matrix in the lepton sector has a similar structure as the …
