【 摘 要 】

In a 𝑅-parity violating (RPV) model of neutrino mass with three bilinear couplings 𝜇𝑖 and three trilinear couplings 𝜆′𝑖33, where 𝑖 is the lepton index, we find six generic scenarios each with a distinctive pattern of the trilinear couplings consistent with the neutrino oscillation data. These patterns may be reflected in direct RPV decays of the lighter top squark or in the RPV decays of the lightest superparticle, assumed to be the lightest neutralino. Typical signal sizes at the Tevatron RUN II and the LHC have been estimated and the results turn out to be encouraging.
