  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.
