Abstract

We study the impact of Leptogenesis on Gravitational Waves from phase transition. We consider a heavy scalar field that decays into radiation and heavy right-handed neutrinos. These heavy right-handed neutrinos decay eventually and generate the lepton asymmetry. A part of the lepton asymmetry transfers into the baryon asymmetry of the Universe via the sphaleron transitions. We identify the parameter space of Leptogenesis where it maybe probed due to the Gravitational Wave spectral shapes. We show that a Gravitational Wave signal which can be detectable in the low-frequency range of future predictions of LISA that is consistent with Leptogenesis.
