Effects of reheating on leptogenesis
We study the evolution of a cosmological baryon asymmetry in leptogenesis when the right-handed neutrinos are produced in inflaton decays. By performing a detailed numerical study over a broad range of inflaton-neutrino couplings we show that the resulting asymmetry can be larger by two orders of magnitude or more than in thermal leptogenesis, if the reheating temperature TRH is of the same ord...
متن کاملReheating-temperature independence of cosmological baryon asymmetry in Affleck-Dine leptogenesis
In this paper we point out that the cosmological baryon asymmetry in our universe is generated almost independently of the reheating temperature TR in Affleck-Dine leptogenesis and it is determined mainly by the mass of the lightest neutrino, mν1, in a wide range of the reheating temperature TR ≃ 105–1012 GeV. The present baryon asymmetry predicts the mν1 in a narrow region, mν1 ≃ (0.3– 1) × 10...
متن کاملOn Higgs and sphaleron effects during the leptogenesis era
We discuss the effects of various processes that can be active during the leptogenesis era, and present the Boltzmann equations that take them into account appropriately. A non-vanishing Higgs number asymmetry is always present, enhancing the washout of the lepton asymmetry. This is the main new effect when leptogenesis takes place at T > 10 GeV, reducing the final baryon asymmetry and tighteni...
متن کاملSneutrino Inflation in the Light of WMAP: Reheating, Leptogenesis and Flavour-Violating Lepton Decays
We reconsider the possibility that inflation was driven by a sneutrino the scalar supersymmetric partner of a heavy singlet neutrino in the minimal seesaw model of neutrino masses. We show that this model is consistent with data on the cosmic microwave background (CMB), including those from the WMAP satellite. We derive and implement the CMB constraints on sneutrino properties, calculate reheat...
متن کامل8 Leptogenesis , Z ′ bosons , and the reheating temperature of the Universe
We study the impact for leptogenesis of new U(1) gauge bosons coupled to the heavy Majorana neutrinos. They can significantly enhance the efficiency of thermal scenarios in the weak washout regime as long as the Z ′ masses are not much larger than the reheating temperature (MZ′ < 10Trh), with the highest efficiencies obtained for Z ′ bosons considerably heavier than the heavy neutrinos (MZ′ & 1...
