标题： Cosmological attractor inflation from the RG-improved Higgs sector of finite gauge theory

摘要： 研究了基于有限规范模型的 Higgs 部分对应的重正化群改进势构造膨胀场景的可能性。 考虑到重正化群势中的量子修正（该势能将微扰论的所有主要对数求和）对于成功实现膨胀场景至关重要，并且所需的参数值非常合理。 所得到的膨胀模型与最近最精确的观测数据非常吻合。 更具体地说，相关的膨胀参数 $n_s$ 和 $r$ 的值接近于 $R^2$ 和 Higgs 驱动的膨胀场景中的相应值。 结果表明，这里构建的模型和 Higgs 驱动的膨胀属于同一类宇宙吸引子。 显示英文摘要

摘要： The possibility to construct an inflationary scenario for renormalization-group improved potentials corresponding to the Higgs sector of finite gauge models is investigated. Taking into account quantum corrections to the renormalization-group potential which sums all leading logs of perturbation theory is essential for a successful realization of the inflationary scenario, with very reasonable parameter values. The inflationary models thus obtained are seen to be in good agreement with the most recent and accurate observational data. More specifically, the values of the relevant inflationary parameters, $n_s$ and $r$, are close to the corresponding ones in the $R^2$ and Higgs-driven inflation scenarios. It is shown that the model here constructed and Higgs-driven inflation belong to the same class of cosmological attractors.
