N2 - The Split-Family supersymmetry is a model in which the sfermion masses of the first two generations are in O(100-1000)GeV while that of the third one is in O(10) TeV. With such a hierarchical spectrum, the deviation of the muon g- 2 and the observed Higgs boson mass are explained simultaneously. In this paper, we revisit the Split-Family SUSY model in light of the updated LHC constraints. We also study the flavor changing neutral current problems in the model. As we will show, the problems do not lead to stringent constraints when the Cabibbo-Kobayashi-Maskawa matrix is the only source of the flavor mixing. We also study how large flavor mixing in the supersymmetry breaking parameters is allowed.
