This work advocates one intriguing possibility for a consistent cosmology that fills in the theoretical gaps while being fully in accordance with the observational data. At very high energies, the universe might have been in a false vacuum state that preserved B-L, the difference between the baryon number B and the lepton number L as a local symmetry. In this state, the universe experienced a stage of hybrid inflation that only ended when the false vacuum became unstable and decayed, in the course of a waterfall transition, into a phase with spontaneously broken B-L symmetry. This B-L Phase Transition was accompanied by tachyonic preheating that transferred almost the entire energy of the false vacuum into a gas of B-L Higgs bosons, which in turn decayed into heavy Majorana neutrinos. Eventually, these neutrinos decayed into massless radiation, thereby producing the entropy of the hot big bang, generating the baryon asymmetry of the universe via t | | 出版日期 | Book 2014 | | 关键词 | Boltzmann Equations; Cosmological Phase Transition; False Vacuum Decay; Gravitino / WIMP Dark Matter; Hy | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-319-00963-6 | | isbn_softcover | 978-3-319-37686-8 | | isbn_ebook | 978-3-319-00963-6Series ISSN 2190-5053 Series E-ISSN 2190-5061 | | issn_series | 2190-5053 | | copyright | Springer International Publishing Switzerland 2014 |
