论文摘要
我们研究了在存在$ r^2 $术语的情况下，在重力表述中，非最小的Coleman-Weinberg通货膨胀。普朗克量表是通过其非最小值耦合到曲率标量$ r $ $ $ $ $ $ $ $ $ $ r $的真空期望值动态产生的。我们表明，在palatini重力中添加$ r^2 $术语使非最小的Coleman-Weinberg通货膨胀再次与观察数据兼容。
We study non-minimal Coleman-Weinberg inflation in the Palatini formulation of gravity in the presence of an $R^2$ term. The Planck scale is dynamically generated by the vacuum expectation value of the inflaton via its non-minimal coupling to the curvature scalar $R$. We show that the addition of the $R^2$ term in Palatini gravity makes non-minimal Coleman-Weinberg inflation again compatible with observational data.
