Abstract

After the discovery of SM-like Higgs with mh=125m_{h}=125 GeV, it is increasingly urgent to explore a solution to the hierarchy problem. In the context of MSSM from gauge-mediated SUSY breaking, the lower bound on gluino mass suggests that the messenger scale MM is probably large if the magnitude of Λ100\Lambda\sim 100 TeV. In this paper, we study 5+5\overline{\mathbf{5}}+ \mathbf{5} model with M1081012M\sim 10^{8}-10^{12} GeV and Λ100\Lambda\simeq 100 TeV. For moderate Higgs-messenger coupling, it will be shown a viable model with moderate fine tuning. In this model, μ800\mu\sim 800 GeV and BμB_{\mu} nearly vanishes at input scale, which can be constructed in microscopic model.
