Relating Leptogenesis to Low Energy CP Violation
Abstract. In the minimal left-right symmetric model with spontaneous CP violation, there are only two intrinsic CP violating phases to account for all CP violation in both the quark and lepton sectors. In addition, the leftand right-handed Majorana mass terms for the neutrinos are proportional to each other due to the parity in the model. This is thus a very constrained framework, making the ex...
متن کاملCP Violation in the SUSY Seesaw: Leptogenesis and Low Energy
We suppose that the baryon asymmetry is produced by thermal leptogenesis (with flavour effects), at temperatures∼ 109−1010 GeV, in the supersymmetric seesaw with universal and real soft terms. The parameter space is restricted by assuming that lα → lβγ processes will be seen in upcoming experiments. We study the sensitivity of the baryon asymmetry to the phases of the lepton mixing matrix, and ...
متن کاملLeptogenesis and Low Energy CP Violation in Neutrino Physics
Taking into account the recent progress in the understanding of the lepton flavour effects in leptogenesis, we investigate in detail the possibility that the CP-violation necessary for the generation of the baryon asymmetry of the Universe is due exclusively to the Dirac and/or Majorana CP-violating phases in the PMNS neutrino mixing matrix U , and thus is directly related to the low energy CP-...
متن کاملA relation between CP violation of low energy and leptogenesis
CP violation at low energy is observed in K and B system. In the future neutrino oscillation experiments , CP asymmetry of the neutrino oscillations P (νi → νj) 6= P (ν̄i → ν̄j) may be also measured. Our question is how low energy CP violation measurements are related to CP violation for Baryon number asymmetry. Fukugita and Yanagida proposed a scenario for Baryon number asymmetry based on the se...
متن کاملCP Violation and Leptogenesis
The origin of the baryon asymmetry of the Universe is one of the key open questions to be addressed in particle physics and cosmology. Assuming a negligible initial baryon asymmetry, its dynamical production can happen in presence of non-conservation of the baryon and/or lepton number, violation of the C and CP symmetries and out-of-equilibrium conditions. Leptogenesis is a mechanism, proposed ...
