本文针对DESI和ACT测量显示谱指数ns偏好值变化、排斥部分流行暴胀模型的问题，结合Coleman-Weinberg有效势分析含量子修正的暴胀模型预测与似然分析，构建了更成熟的预测框架。
AI 中文摘要
近期DESI和ACT等宇宙学测量的进展，可能表明谱指数ns的偏好值有所增加，这使得它不再支持希格斯或Starobinski暴胀模型等流行模型。我们认为这实际上意味着数据现在足够敏感，能够探测到超出简单树级模型的量子修正。我们重拾Coleman-Weinberg有效势这一旧主题，分析此类模型的预测及似然分析，进而形成一个更成熟且有趣的预测框架。
英文摘要
Recent advances in cosmological measurements such as DESI and ACT may indicate an increase in the preferred value of the spectral tilt $n_s$ such that it disfavors rather popular models such as the Higgs or Starobinski inflation models. We argue that it actually means that the data is now sensitive enough to quantum corrections beyond simple tree-level models. Resurrecting the old theme of Coleman-Weinberg effective potential, we analyze the predictions of such models, as well as likelihood analysis, leading to a more established and interesting predictive framework.
