Effects of the neutrino B term on slepton mixing and electric dipole moments

The supersymmetric standard model with right-handed neutrino supermultiplets generically contains a soft supersymmetry breaking mass term: $\delta {L=B}_{\nu }M{\tilde{\nu }}_R{\tilde{\nu }}_R/2.\mathrm{}$ We call this operator the “neutrino B term.” We show that the neutrino B term can give the dominant effects from the neutrino sector to lepton-flavor-violating processes and to lepton electric dipole moments.
