We investigate the LHC sensitivity to supersymmetric models with lighthiggsinos, small R-parity breaking and gravitino dark matter. The limits ondecaying gravitino dark matter from gamma-ray searches with the Fermi-LAT put alower bound on the higgsino-like neutralino NLSP decay length, giving rise to adisplaced-vertex collider signature. Using publicly available tools forsimulation of signal, background and detector response, we find that higgsinoswith masses of 100-400 GeV and R-parity violation of approximately 10^-8 to10^-9 can show up in the 8 TeV LHC data with 10-30 fb^-1 of integratedluminosity. We demonstrate that in the case of a signal, the higgsino mass canbe determined by reconstruction of the dimuon mass edge.
