摘要

爱因斯坦广义相对论的一个特殊扩展，包括曲率张量中的四次项，在某种意义上是最小的，它有一个独特的最大对称真空，在真空周围的光谱中只有一个无质量的自旋-2激发。在标准模型场和最小超对称标准模型场中存在的微量异常项的情况下，我们研究了爱因斯坦引力的最小四次扩展中宇宙的暴胀相。我们证明了该理论允许具有足够电子折叠的准德西特相。

Anomaly induced inflation in the minimal quartic extension of Einstein’s gravity

A particular extension of Einstein’s General Relativity up to and including quartic terms in the curvature tensor is minimal in the sense that it has a unique maximally symmetric vacuum and only a massless spin-2 excitation in its spectrum around the vacuum. We study the inflation phase of the universe in this minimal quartic extension of Einstein’s gravity in the presence of trace anomaly terms coming from the Standard Model fields and the fields of the Minimal Supersymmetric Standard Model. We show that the theory allows a quasi-de Sitter phase with sufficient e-foldings.
