利用弯曲时空中自相互作用标量场理论的双圈有效势研究了混沌暴胀模型。我们使用的势包含一个非最小的标量曲率耦合和一个四次标量自相互作用，这是发现在参考。[1]的文件。我们分析了de Sitter解的李雅普诺夫稳定性，并给出了稳定性界.通过计算暴胀参数，系统地研究了谱指数ns和张量标量比r随标量曲率耦合λ 0、标量四次耦合λ 0、重整化尺度μ和e折叠数N四个参数的变化.研究发现，双回线对ns的修正远大于先导对数修正，而先导对数修正在文献[1]中已有研究。[2]的文件。我们表明，该模型与普朗克与WMAP [3]，[4]以及最近对BICEP 2 [5]的联合分析的观测结果一致。
We investigate the chaotic inflationary model using the two-loop effective potential of a self-interacting scalar field theory in curved spacetime. We use the potential which contains a non-minimal scalar curvature coupling and a quartic scalar self-interaction and which was found in Ref.[1]. We analyze the Lyapunov stability of de Sitter solution and show the stability bound. Calculating the inflationary parameters, we systematically explore the spectral index n s and the tensor-to-scalar ratio r, with varying the four parameters, the scalar-curvature coupling ξ 0, the scalar quartic coupling λ 0, the renormalization scale μ and the e-folding number N. It is found that the two-loop correction on n s is much larger than the leading-log correction, which has previously been studied in Ref.[2]. We show that the model is consistent with the observation by Planck with WMAP [3],[4] and a recent joint analysis of BICEP2 [5].
