关于单场暴胀中三点函数的相容关系

On the consistency relation of the 3-point function in single field inflation

Clifford Cheung, A. Liam Fitzpatrick, Jared Kaplan, Leonardo Senatore

摘要:

CMB的三点函数的相容性关系是一个非常强大的观测信号,它被认为适用于每个只有一个动力学自由度的暴胀模型。它的重要性依赖于这样一个事实,即在下一代实验中可能会检测到与它的偏差,从而使我们能够排除所有单场暴胀模型。在对已有的相容性关系的证明作了更精确的证明之后,我们利用最近发展起来的暴胀微扰的有效场论,提供了另一种在慢滚参数的非平凡阶有效的非常明确的证明.

英文摘要:

The consistency relation for the 3-point function of the CMB is a very powerful observational signature which is believed to be true for every inflationary model in which there is only one dynamical degree of freedom. Its importance relies on the fact that deviations from it might be detected in next generation experiments, allowing us to rule out all single field inflationary models. After making more precise the already existing proof of the consistency relation, we use a recently developed effective field theory for inflationary perturbations to provide an alternative and very explicit proof valid at leading non trivial order in slow roll parameters.
