论文摘要
CMB的最新观察结果对通货膨胀模型的张/标量比$ r $ r $ r <0.064 $施加了非常严格的上限，这表明原始引力波（PGW），即使可以检测到的原始引力波（PGW）也应该具有较小的振幅的功率谱。但是，当前关于PGW的实验是雄心勃勃的，可以通过将精度提高到更高的水平来检测这种信号。无论它们是什么结果，它都将为我们提供有关早期宇宙的大量信息，不仅是从天体物理方面，而且从理论方面，例如早期宇宙的模型构建。在本文中，我们有兴趣分析未来的观察可以利用哪种通货膨胀模型，从有效的现场理论（EFT）方法提供的一种通用行动开始。我们显示了可以简化为各种模型的$ r $的一般形式，更重要的是，我们展示了未来观察的准确性如何通过在其参数空间中绘制轮廓来对模型参数构成约束。
The recent observations from CMB have imposed a very stringent upper-limit on the tensor/scalar ratio $r$ of inflation models, $r < 0.064$, which indicates that the primordial gravitational waves (PGW), even though possible to be detected, should have a power spectrum of a tiny amplitude. However, current experiments on PGW is ambitious to detect such a signal by improving the accuracy to an even higher level. Whatever their results are, it will give us much information about the early Universe, not only from the astrophysical side but also from the theoretical side, such as model building for the early Universe. In this paper, we are interested in analyzing what kind of inflation models can be favored by future observations, starting with a kind of general action offered by the effective field theory (EFT) approach. We show a general form of $r$ that can be reduced to various models, and more importantly, we show how the accuracy of future observations can put constraints on model parameters by plotting the contours in their parameter spaces.
