本文致力于调和自然性的理论期望与目前LHC对超伴体质量界的极限之间的紧张关系。我们认为,在直接规范中介的超对称模型中,出现了聚焦现象,这大大减少了与126 GeV希格斯玻色子相关的微调。这类模型在质谱方面具有很高的预测性,具有多TeV的第三代,1 TeV数量级,胶子质量高于LHC质量界,轻中性子和带电子低于1 TeV。
This paperis devoted to the reconciliation of the tension between the theoretic expectation from naturalness and the present LHC limits on the superpartner mass bounds. We argue that in supersymmetry models of direct gauge mediation the focusing phenomenon appears, which dramatically reduces the fine tuning associated to the 126 GeV Higgs boson. This type of model is highly predictive as regards the mass spectrum, with a multi-TeV third generation, theterm of order 1 TeV, gluino mass above LHC mass bound, and the light neutralinos and charginos below 1 TeV.
