Asymmetric lepton production in a universe with non-zero baryon number

  • 29 Accesses

  • 4 Citations


It is pointed out that as a result of processes during different stages of stellar evolution a universe with a net baryon number develops during a Hubble age an excess of neutrinos over antineutrinos of the same order as the observed relative strength of CP violation. The same processes also favour excess positron production.
