Neutrino masses from a pseudo-Dirac Bino

Abstract

We show that, in $U(1{)}_R$-symmetric supersymmetric models, the bino and its Dirac partner (the singlino) can play the role of right-handed neutrinos and generate the neutrino masses and mixing, without the need for traditional bilinear or trilinear R-parity violating operators. The two particles form a pseudo-Dirac pair, the `bi$\nu$o'. An Inverse Seesaw texture is generated for the neutrino-bi$\nu$o sector, and the lightest neutrino is predicted to be massless. Unlike in most models with heavy right-handed neutrinos, the bi$\nu$o can be sizably produced at the LHC through its interactions with colored particles, while respecting low energy constraints from neutrinoless double-beta decay and charged lepton flavor violation.
