我们调查的预测与非最小耦合的暴胀模型的重力暴胀观测,如光谱指数和张量标量比在一般设置。我们认为,根据约旦框架潜力和一个功能之间的关系表征的非最小耦合,可以将模型分为三类,每一类都给出了独特的预测的通货膨胀的观测。我们得到一般的预测,为每一类,也调查了一些明确的模型,讨论如何产生的一般功能。我们的结果将有助于设计一个膨胀模型与观测约束一致的非最小耦合重力。
We investigate the predictions of inflation models with a nonminimal coupling to gravity for inflationary observables such as the spectral index and tensor-to-scalar ratio in a general setting. We argue that, depending on the relation between the Jordan frame potential and a function characterizing the nonminimal coupling, one can classify the model into three categories, each of which gives distinctive predictions for the inflationary observables. We derive general predictions for each class and also investigate some explicit models to discuss how the general features arise. Our results would be useful to design an inflation model consistent with observational constraints with a nonminimal coupling to gravity.
