Constraints on the R-Parity violating minimal supersymmetric standard
model with neutrino masses from multi-lepton studies at the LHC    [PDF]

M. Hanussek, J. S. Kim

In a recent paper, we proposed a hierarchical ansatz for the lepton-number violating trilinear Yukawa couplings of the R-parity violating minimal supersymmetric standard model. As a result, the number of free parameters in the lepton-number violating sector were reduced from 36 to 6. Neutrino oscillation data fixes these 6 parameters, which also uniquely determines the decay modes of the lightest supersymmetric particle and thus governs the collider signature at the LHC. A typical signature of our model consists of multiple leptons in the final state and significantly reduced missing transverse momentum compared to models with R-parity conservation. In this work, we present exclusion limits on our model based on multi-lepton searches performed at the Large Hadron Collider with 7 TeV center-of-mass energy in 2011 while accommodating a 125 GeV Higgs.
