论文摘要
在本文中，我们提供了混合膨胀的无尺度超级强度方案，而R-对称性最大损坏。我们研究了两种纯F-期杂种膨胀情况的详细信息的通胀动态，以及添加恒定的fayet-iliopoulos d-terms时的通胀动态。在两种情况下，在参数空间的一个区域中，有效的通胀电位渐近地平坦。在讨论可观察到的约束时，我们会探索参数空间中的所有区域。我们指出通货膨胀，R-对称性断裂和肠道尺度之间的联系。在特定的稳定机制中研究了模量反应和SUSY断裂效应。我们强调，成功的再加热不受R-Asmortry Breaking的影响，但它具有有趣的后果。我们研究翻转肠模型的加热。我们争辩说$ z_2 $对称性与翻转的肠模型相关，以避免现象学上危险的操作员，并允许发电量的衰减通道到右手中微子（Sneutrinos）。
In this paper we provide a no-scale supergravity scenario of hybrid inflation with R-symmetry being broken maximally. We investigate the inflation dynamics in details in both cases of pure F-term hybrid inflation and when adding constant Fayet-Iliopoulos D-terms. The effective inflation potential is asymptotically flat in a region of the parameter space in both cases. We explore all regions in the parameter space when discussing the constraints from the observables. We point out a connection between inflation, R-symmetry breaking and GUT scales. The moduli backreaction and SUSY breaking effects are investigated in a specific stabilization mechanism. We emphasis that a successful reheating is not affected by R-symmetry breaking, but it has interesting consequences. We study the reheating in flipped GUT model. We argue in favor of $Z_2$ symmetry associated with flipped GUT models to avoid phenomenologically dangerous operators and allow for decay channels for the inflaton to right-handed neutrinos (sneutrinos).
