标题： F-Term Hybrid Inflation and SUSY Breaking

摘要： 我们考虑在很大程度上尊重全局U(1) R对称性的模型中的F项混合膨胀和超对称性破缺。 Kähler势通过一个增强的U(1)_Rx(SU(1,1)/U(1))对称性参数化Kähler流形，其中第二个因子的标量曲率由无丑陋调节的超对称性破缺的De Sitter真空实现。 暴胀子的出现的软 tadpole 项的大小可以在(1.2-460) TeV范围内调整——随着瀑布场表示的维度增加而增大——从而使膨胀观测值与观测要求一致。 超对称伙伴的质量尺度位于(0.09-253) PeV区域，这与高能标超对称性和LHC对希格斯玻色子质量的结果相容。 μ参数可以通过方便地应用Giudice-Masiero机制生成，并确保R saxion在低再加热温度Trh<163 GeV下非平衡衰变。 显示英文摘要

摘要： We consider F-term hybrid inflation and supersymmetry breaking in the context of a model which largely respects a global U(1) R symmetry. The Kaehler potential parameterizes the Kaehler manifold with an enhanced U(1)_Rx(SU(1,1)/U(1)) symmetry, where the scalar curvature of the second factor is determined by the achievement of a supersymmetry-breaking de Sitter vacuum without ugly tuning. The magnitude of the emergent soft tadpole term for the inflaton can be adjusted in the range (1.2-460) TeV -- increasing with the dimensionality of the representation of the waterfall fields -- so that the inflationary observables are in agreement with the observational requirements. The mass scale of the supersymmetric partners turns out to lie in the region (0.09-253) PeV which is compatible with high-scale supersymmetry and the results of LHC on the Higgs boson mass. The mu parameter can be generated by conveniently applying the Giudice-Masiero mechanism and assures the out-of-equilibrium decay of the R saxion at a low reheat temperature Trh<163 GeV.
