摘要: We present the effective field theory studies of primordial statistical anisotropies in models anisotropic inflation. The general action unitary gauge is presented to calculate leading interactions between fluctuations, curvature perturbations and tensor perturbations. scalar power spectrum bispectrum are calculated dependence these EFT couplings presented. In addition, we anisotropy scalar-tensor cross correlation. Our approach incorporates generated with non-trivial speed for fluctuations sound such as DBI
