摘要: Effect of non-canonical scalar fields on the CMB imprints anisotropic inflation will be discussed in details this paper. In particular, we are able to obtain general formalism angular power spectra perturbations, tensor cross-correlations, and linear polarization context model involving fields. Furthermore, some significant numerical plotted using most recent data Planck as well BICEP2 Keck array. As a result, find very interesting point that $TT$ induced by perturbations increase when speed sound decreases.
