Correlation functions of sourced gravitational waves in inflationary scalar vector models. A symmetry based approach
Abstract We use conformal symmetry to constrain the shape of inflationary correlators in the presence of long-lived vector field perturbations. Applying conformal Ward identities, we derive general expressions, up to amplitudes and normalization factors, for the two and three-point correlators in th...
