Impact of high-scale Seesaw and Leptogenesis on inflationary tensor perturbations as detectable gravitational waves

Abstract We discuss the damping of inflationary gravitational waves (GW) that re-enter the horizon before or during an epoch, where the energy budget of the universe is dominated by an unstable right handed neutrino (RHN), whose out of equilibrium decay releases entropy. Starting from the minimal St...
