Description:
Author(s): Peter Adshead, Emil Martinec, and Mark Wyman Models of inflation involving non-Abelian gauge field backgrounds can produce gravitational waves at an observable level with a preferred handedness. This asymmetry comes about because the non-Abelian background generates parity violation in the action for perturbations. In the specific model we stu... [Phys. Rev.
