  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 was reduced from 36 to 6.
Neutrino oscillation data fixes these six 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 multilepton
searches performed at the Large Hadron Collider with 7 TeV center-of-mass
energy in 2011 while accommodating a 125 GeV Higgs.
