论文摘要
我们最近提出了基于无尺度超级重力的模量固定，通货膨胀，超对称性断裂和暗能量的吸引力模型。在本文中，我们开发了这些基于其物理应用的无尺度吸引者模型的现象学和宇宙学方面。我们考虑通过模量字段（$ t $ type）驱动通货膨胀的模型，其中polonyi场或物质字段（$ ϕ $ -Type）损坏了超对称性，而模量域则损坏了超对称性。我们得出了柔软超对称性术语的可能模式，这些术语是否取决于$ t $ type模型，无论Polonyi和/或“物质”字段是否扭曲，以及$ ϕ $ -Type模型，涉及Efteraton和/或其他物质领域是否扭曲。在$ ϕ $ -Type型号中，我们能够将超对称分解的规模直接与加速器质量联系起来。我们还讨论了熵考虑的宇宙学限制和通过无尺度的kähler潜力中高阶项稳定模量场的暗物质的密度。
We have recently proposed attractor models for modulus fixing, inflation, supersymmetry breaking and dark energy based on no-scale supergravity. In this paper we develop phenomenological and cosmological aspects of these no-scale attractor models that underpin their physical applications. We consider models in which inflation is driven by a modulus field ($T$-type) with supersymmetry broken by a Polonyi field, or a matter field ($ϕ$-type) with supersymmetry broken by the modulus field. We derive the possible patterns of soft supersymmetry-breaking terms, which depend in $T$-type models whether the Polonyi and/or matter fields are twisted or not, and in $ϕ$-type models on whether the inflaton and/or other matter fields are twisted or not. In $ϕ$-type models, we are able to directly relate the scale of supersymmetry breaking to the inflaton mass. We also discuss cosmological constraints from entropy considerations and the density of dark matter on the mechanism for stabilizing the modulus field via higher-order terms in the no-scale Kähler potential.
