论文摘要
本文将详细讨论非规范标量场对各向异性通货膨胀的CMB烙印的影响。特别是，我们能够在标量扰动，张量扰动，互相关和线性极化中获得角度功率光谱的一般形式，在涉及非经典标量场的各向异性膨胀模型的背景下。此外，使用普朗克以及二头肌和凯克阵列的最新数据绘制一些重要的数值光谱。结果，我们发现一个非常有趣的观点是，当声音速度降低时，张量扰动引起的$ TT $光谱以及线性极化将增加。
Effect of non-canonical scalar fields on the CMB imprints of the anisotropic inflation will be discussed in details in this paper. In particular, we are able to obtain the general formalism of the angular power spectra in the scalar perturbations, tensor perturbations, cross-correlations, and linear polarization in the context of the anisotropic inflation model involving non-canonical scalar fields. Furthermore, some significant numerical spectra will be plotted using the most recent data of Planck as well as the BICEP2 and Keck array. As a result, we find a very interesting point that the $TT$ spectra induced by the tensor perturbations as well as by the linear polarization will increase when the speed of sound decreases.
