The TT, TB, EB and BB correlations in anisotropic inflation

Chen, Xingang, Emami, Razieh, Firouzjahi, Hassan et al.

Understand

The ongoing and future experiments will measure the B-mode from different sky coverage and frequency bands, with the potential to reveal non-trivial features in polarization map.

In this work we study the TT, TB, EB and BB correlations associated with the B-mode polarization of CMB map in models of charged anisotropic inflation.
The model contains a chaotic-type large field complex inflaton which is charged under the $U(1)$ gauge field.
We calculate the statistical anisotropies generated in the power spectra of the curvature perturbation, the tensor perturbation and their cross-correlation.
