Primordial power spectrum of tensor perturbations in Finsler spacetime
Source PublicationEUROPEAN PHYSICAL JOURNAL C
Language英语
AbstractWe first investigate the gravitational wave in the flat Finsler spacetime. In the Finslerian universe, we derive the perturbed gravitational field equation with tensor perturbations. The Finslerian background spacetime breaks rotational symmetry and induces parity violation. Then we obtain the modified primordial power spectrum of the tensor perturbations. The parity violation feature requires that the anisotropic effect contributes to the TT, T E, EE, BB angular correlation coefficients with l' = l + 1 and T B, EB with l' = l. The numerical results show that the anisotropic contributions to the angular correlation coefficients depend on m, and T E and ET angular correlation coefficients are different.
