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

Abstract

An R-parity violating SUSY model with lepton-number violating couplings $\hat{I}{»}_{i33}^{\prime }$, 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 $3\ddot{I}ƒ$ up to $m_{1/2}=230$ GeV (320 GeV) with an integrated luminosity of $2f{b}^{-1}$ ($30f{b}^{-1}$).
