R parity violating supersymmetric explanation for the CDF Wjj excess

Understand

Recently CDF has reported a 4.1 sigma excess in the distribution of the dijet invariant mass between 120-160 GeV in Wjj event sample in 7.3 fb^{-1} of data, which has generated considerable interest.

• We offer a possible explanation of this observation in the general framework of MSSM with R-parity violation through resonance production of tau sneutrino decaying into the LSP stau_1 and W boson.
• We also give the predictions of this scenario for the LHC operating at 7 TeV center of mass energy.
