oai:localhost:PNK-18852022-08-17T05:54:44Z CMB imprints of non-canonical anisotropic inflation Tuan Q. Do W. F. Kao Ing-Chen Lin Q1 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. 2021-06-21T02:45:11Z 2021-06-21T02:45:11Z 2021 Article Working Paper https://link.springer.com/article/10.1140%2Fepjc%2Fs10052-021-09181-x https://dlib.phenikaa-uni.edu.vn/handle/PNK/1885 10.1140/epjc/s10052-021-09181-x en application/pdf The European Physical Journal C |
