Abstract: We study the seesaw mechanism in the supersymmetric standard model (SSM) with symmetry instead of the R-parity, so-called {it Matter triality} (). This Abelian discrete symmetry prohibits the baryon/lepton number violation operators at the non-renormalizable level, and the proton longevity is ensured. The lepton number violation term by the right-handed neutrino is only allowed under the symmetry, it plays a role of the Majorana mass after the right-handed sneutrino develops into the vacuum expectation value. The mass of the active neutrino is generated from the two contributions from the right-handed neutrino and the neutralino due to the R-parity violation. In this paper, we realize the neutrino mass and mixing angle in the SSM with matter triality which is embedded into the gauged flavor symmetry. In addition to the flavor ansatz, we derive the charge assignment to satisfy the anomaly cancellation conditions. Then, the model could predict the sterile neutrino with the mass below the soft SUSY breaking mass scale, and its mass and mixing angle are restricted by the search for the heavy neutral leptons.
