Abstract

We discuss the minimal supersymmetric standard model with "split-family" spectrum where the sfermions in the first two generations are in the hundreds GeV to a TeV range while the sfermions in the third generation are in the range of tens TeV. With the split-family spectrum, the deviation of the muon g-2 and the observed Higgs boson mass are explained simultaneously. It is predicted that the gluino and the squarks in the first two generations are within the reach of the LHC experiments in most favored parameter space for the universal gaugino mass, which can be tested by searching for events with missing transverse energy or events with stable charged massive particles. We also point out that the split-family scenario can be consistent with the focus point scenario for the non-universal gaugino masses where the required mu-term is in the hundreds GeV range.
