摘要:

我们总结了精确的宇宙微波背景(CMB)偏振测量作为暴胀物理探测器的效用。我们专注于使用CMB测量来区分各种通货膨胀机制的前景。特别是,原始B模式偏振的检测将证明暴胀发生在非常高的能量尺度上,并且暴胀子在场空间中穿过超普朗克距离。我们解释了如何这样的检测或约束将照亮物理学方面的普朗克尺度。此外,CMB测量可以限制原始波动的尺度依赖性和非高斯性,并限制显着的等曲率贡献的可能性。每一个这样的限制都提供了关于潜在通货膨胀动态的关键信息。最后,我们量化这些考虑提出预测未来的卫星实验的通货膨胀参数的敏感性。

英文摘要:

We summarize the utility of precise cosmic microwave background (CMB) polarization measurements as probes of the physics of inflation. We focus on the prospects for using CMB measurements to differentiate various inflationary mechanisms. In particular, a detection of primordial B-mode polarization would demonstrate that inflation occurred at a very high energy scale, and that the inflaton traversed a super-Planckian distance in field space. We explain how such a detection or constraint would illuminate aspects of physics at the Planck scale. Moreover, CMB measurements can constrain the scale-dependence and non-Gaussianity of the primordial fluctuations and limit the possibility of a significant isocurvature contribution. Each such limit provides crucial information on the underlying inflationary dynamics. Finally, we quantify these considerations by presenting forecasts for the sensitivities of a future satellite experiment to the inflationary parameters.
