We assess the future directions for the search for supersymmetry at the Large\nHadron Collider in view of the new precision results on the muon anomaly by the\nFermilab Collaboration. The existence of a deviation of size 4.1\σ from\nthe Standard Model prediction points to light sleptons and light weakinos in\nthe mass range of few hundred GeV while the observation of the Higgs boson mass\nat \∼ 125 GeV points to squark masses lying in the few TeV range. Thus a\nsplit sparticle spectrum is indicated. We discuss the possibility of such a\nsplit sparticle spectrum in the supergravity unified model and show that a\nsplitting of the sfermion spectrum into light sleptons and heavy squarks\nnaturally arises within radiative breaking of the electroweak symmetry driven\nby heavy gluinos ( gSUGRA). We discuss the possible avenues for the\ndiscovery of supersymmetry at the LHC within this framework under the further\nconstraint of the recent muon anomaly result from the Fermilab Collaboration.\nWe show that the most likely candidates for early discovery of a sparticle at\nthe LHC are the chargino, the stau, the smuon and the selectron. We present a\nset of benchmarks and discuss future directions for further work. Specifically,\nwe point to the most promising channels for SUSY discovery and estimate the\nintegrated luminosity needed for the discovery of these benchmarks at the High\nLuminosity LHC and also at the High Energy LHC.\n
