Throwing away antimatter via neutrino oscillations during the reheating era

16 Sep 2019 Eijima Shintaro Kitano Ryuichiro Yin Wen

The simplest possibility to explain the baryon asymmetry of the Universe is to assume that radiation is created asymmetrically between baryons and anti-baryons after the inflation. We propose a new mechanism of this kind where CP-violating flavor oscillations of left-handed leptons in the reheating era distribute the lepton asymmetries partially into the right-handed neutrinos while net asymmetry is not created...
