Abstract
We discuss our new theory on baryogenesis `Type-II leptogenesis' \cite{CoviKim16} which is different from the well-known `Type-I leptogenesis' \cite{FY86}. First, we will briefly comment on the Jarlskog phases in the CKM and PMNS matrices, $\delta_{CKM}$ and $\delta_{PMNS}$. Then, the PMNS phase is used in the `Type-II' leptogenesis for Sakharov's condition on the global quantum number generation in the Universe. For this to be effective, the SU(2)$\times$U(1) gauge symmetry must be broken during the leptogenesis epoch.
