论文摘要
在本文中，我们研究了四个混凝土模型，这些模型基于NOCALE SUPERGRAVITY，su（2,1）/su（2）$ \ times $ u（1）对称性。我们修改了Kähler电位或超电势，这与这种对称性相关。在这种情况下，诱导的引力波被计算为可以通过诸如Lisa，BBO和Decigo之类的未来空间观测值检测到。研究模型相互关联，因为它们都在未修饰的情况下产生了Starobinsky有效的标量潜力。我们以数值评估标量功率谱和重力波的随机背景，满足了通货膨胀的观察性普朗克宇宙学约束。
In this paper we study four concrete models, based on no-scale supergravity with SU(2,1)/SU(2)$\times$ U(1) symmetry. We modify either the Kähler potential or the superpotential, which are related to the no-scale theory with this symmetry. In this scenario, the induced Gravitational Waves, are calculated to be detectable by the future space-based observations such as LISA, BBO and DECIGO. The models under study are interrelated, as they all yield the Starobinsky effective-like scalar potential in the unmodified case. We evaluate numerically the scalar power spectrum and the stochastic background of the Gravitational Waves, satisfying the observational Planck cosmological constraints for inflation.
