Testing radiative neutrino mass generation via R-parity violation at the Tevatron

An R-parity violating SUSY model with lepton-number violating couplings λ′i33, i=2,3, can generate a neutrino mass spectrum that explains the recent results from neutrino oscillation experiments. These R-parity violating couplings lead to a clean signal with at least one isolated lepton and at least three tagged b jets that is accessible in chargino and neutralino production at the Tevatron collider. This signature can be probed at 3σ up to m1/2=230 GeV (320 GeV) with an integrated luminosity of 2 fb−1 (30 fb−1).
