Anisotropic Trispectrum of Curvature Perturbations Induced by Primordial Non-Abelian Vector Fields
Motivated by the interest in models of the early universe where statistical isotropy is broken and can be revealed in cosmological observations, we consider an SU(2) theory of gauge interactions in a single scalar field inflationary scenario. We calculate the trispectrum of curvature perturbations,...
