摘要：

We propose a scenario where only the Higgs multiplets have direct couplings to a supersymmetry (SUSY) breaking sector. The standard model matter multiplets as well as the gauge multiples are sequestered from the SUSY breaking sector; therefore, their masses arise via anomaly mediation at the high energy scale with a gravitino mass of similar to 100 TeV. Due to renormalization group running effects from the Higgs soft masses, the masses of the third generation sfermions become O (10) TeV at the low energy scale, while the first and second generation sfermion masses are O (0.1-1) TeV, avoiding the tachyonic slepton problem and flavor changing neutral current problem. With the splitting mass spectrum, the muon g - 2 anomaly is explained consistently with the observed Higgs boson mass of 125 GeV. Moreover, the third generation Yukawa couplings are expected to be unified in some regions. (C) 2016 The Author(s). Published by Elsevier B.V.
