Testing neutrino masses in the R-parity violating minimal supersymmetric standard model with LHC results

Abstract

Within the R-parity violating minimal supersymmetric standard model (MSSM), we use a hierarchical ansatz for the lepton-number violating trilinear Yukawa couplings by relating them to the corresponding Higgs-Yukawa couplings. This ansatz reduces the number of free parameters in the lepton-number violating sector from 36 to 6. Baryon-number violating terms are forbidden by imposing the discrete gauge symmetry Baryon Triality. We fit the lepton-number violating parameters to the most recent neutrino oscillation data, including the mixing angle theta13 found by Daya Bay. We find that we obtain phenomenologically viable neutrino masses and mixings only in the case of normal ordered neutrino masses and that the lepton-number violating sector is unambiguously determined by neutrino oscillation data. We discuss the resulting collider signals for the case of a neutralino as well as a scalar tau lightest supersymmetric particle. We use the ATLAS searches for multi-jet events and large transverse missing momentum in the 0, 1 and 2 lepton channel with 7 TeV center-of-mass energy in order to derive exclusion limits on the parameter space of this R-parity violating supersymmetric model.
