Baryogenesis through lepton number violation
The most promising scenarios of baryogenesis seems to be the one through lepton number violation. Lepton number violation through a Majarana mass of the right-handed neutrinos can generate a lepton asymmetry of the universe when the righthanded neutrinos decay. The left-handed neutrinos get small Majorana masses through see-saw mechanism in these models. A triplet higgs scalar violating lepton ...
متن کاملBaryogenesis: The Lepton Leaking Mechanism
We propose a baryoand leptogenesis mechanism in which the B−L asymmetry is produced in the conversion of ordinary leptons into particles of some depleted hidden sector. In particular, we consider the lepton number violating reactions lφ→ lφ, l̄φ̄ mediated by the heavy Majorana neutrinos N of the seesaw mechanism, where l and φ are ordinary lepton and Higgs doublets and l, φ the “sterile” leptons ...
متن کاملBaryogenesis via lepton-number-violating scalar interactions.
We study baryogenesis through lepton number violation in left-right symmetric models. In these models the lepton number and CP violating interactions of the triplet higgs scalars can give rise to lepton number asymmetry through non-equilibrium decays of the SU(2)L triplet higgs and the right handed neutrinos. This in turn generates baryon asymmetry during the electroweak anomalous processes. Co...
متن کاملBaryogenesis from a Lepton Asymmetric Universe
We demonstrate that CP−violation in the Majorana mass matrices of the heavy neutrinos can generate a CP−asymmetric universe. The subsequent decay of the Majorana particles generates a lepton number asymmetry. During the electroweak phase transition the lepton asymmetry is converted into a baryon asymmetry, which survives down to this time. 1 On sabbatical leave from Theory Group, Physical Resea...
متن کاملBaryogenesis from a Primordial Lepton Asymmetry
Abstract We examine the generation of baryon asymmetry at the weak scale from a primordial lepton asymmetry. If the electroweak phase transition is first order, partial reflection of tau leptons off the bubble walls and the resulting hypercharge transport into the symmetric phase, gives rise to a baryon number consistent with observation.We examine the generation of baryon asymmetry at the weak...
