论文摘要
$ r+r^2 $重力模型具有爱因斯坦框架中相应浅势的重力模型与观测值一致。最近，已经做出了许多努力来概括通货膨胀的$ r+r^2 $（Starobinsky）模型，或使用其他浅层潜力来为早期宇宙构建模型。我们修改了有关浅层潜力的问题。我们提出了一个模型，其中Starobinsky模型可以通过动力学机制出现。我们表明，幽灵模式的不存在导致对Starobinsky模型参数的约束。我们获得了扩展模型的标量光谱指数和张量比比率，并研究了曲率扰动的三点相关功能，以估计所提出模型的原始非高斯非高斯。
The $R+R^2$ model of gravity with the corresponding shallow potential in the Einstein frame is consistent with the observations. Recently, many efforts have been made to generalize the $R+R^2$ (Starobinsky) model of inflation or use other shallow potentials to construct a model for the early Universe. We revise the question about the shallow potential. We propose a model in which the Starobinsky model can emerge through a dynamical mechanism. We show that the absence of ghost modes results to constraints on the parameters of the Starobinsky model. We obtain the scalar spectral index and the tensor-to-scalar ratio of the extended model and study the three-point correlation function of the curvature perturbation to estimate the primordial non-Gaussianities of the proposed model.
