A at the LHC. We find that while a usual cut-based analysis (CBA) of LHC data worth 300 fb?1 would be unable to discover such excitations, a multivariate analysis (MVA) can be reasonably sensitive to higgsino-like ewinos having masses ? 650 GeV when \( {m}_{{ ilde{t}}_1} \) ? 1 TeV. On the other hand, with 3000 fb?1 of data, these masses become accessible in a CBA while even an MVA on such a data set is unlikely to find these ewinos with masses around 1 TeV when \( {m}_{{ ilde{t}}_1} \) hits ～ 1.5 TeV.
