摘要
We present a simple model that achieves m(h) approximate to 126 GeV in the MSSM with large A-terms and TeV-scale stops through a combination of gauge mediation and Higgsmessenger interactions. The mu/B-mu and A/m(H)(2) problems are both solved by a common mechanism - partial sequestering from strong hidden sector dynamics. Using the framework of General Messenger Higgs Mediation, we explicitly calculate the soft masses in terms of the vacuum expectation values, operator dimensions and OPE coefficients of the strongly-coupled hidden sector. Along the way, we also present a general analysis of the various constraints on sequestered Higgs mediation models. The phenomenology of such models is similar to gaugino mediation, but with large A-terms. The NLSP is always long-lived and is either the lightest stau or the Higgsino. The colored states are typically out of reach of the 8TeV LHC, but may be accessible at 14TeV, especially if the NLSP is the lightest stau.
