Lepton asymmetric universe

نویسندگان

چکیده

The recent observation of $^4$He implies that our universe has a large lepton asymmetry. We consider the Affleck-Dine (AD) mechanism for number generation. In AD mechanism, non-topological solitons called L-balls are produced, and generated is confined in them. protect from being converted to baryon through sphaleron processes. study formation evolution find with asymmetry suggested by measurement can be realized.

Baryogenesis 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...

Lepton asymmetry creation in the Early Universe

Oscillations of active to sterile neutrinos with a small mixing angle sin 2θ < 10 −2 could generate a large lepton asymmetry in the Early Universe. The final order of magnitude of the lepton asymmetry η is mainly determined by its growth in the last stage of evolution, the so called power-law regime. There exist two contradictory results in the literature, η ∝ T −1 and η ∝ T −4 , where T is the...

Lepton Asymmetry of the Universe and Charged Quark-Gluon Plasma

The lepton asymmetry of order one is not excluded experimentally and, if present, can lead to interesting phenomena in the early Universe. It is shown that, when the temperature is above the quark-hadron transition, the lepton asymmetry induces chemical potentials for electric charge and for baryon number, and makes the quarkgluon plasma electrically charged.

Asymmetric Inflationary Reheating and the Nature of Mirror Universe

The existence of a shadow world (or mirror universe) with matter and forces identical to that of the visible world but interacting with the latter only via gravity can be motivated by superstring theories as well as by recent attempts to understand the nature of a sterile neutrino needed if all known neutrino data are to be consistent with each other. A simple way to reconcile the constraints o...

Baryogenesis appears to require lepton number violation. This is naturally realized in extensions of the standard model containing right-handed neutrinos. We discuss the generation of a baryon asymmetry by the out-of-equilibrium decay of heavy Majorana neutrinos in these models, without and with super-symmetry. All relevant lepton number violating scattering processes which can inhibit the gene...
