Abstract
The CP violation observed in K- and B-mesons can be successfully accommodated via the CKM matrix in the standard model. However the additional CP violation is required in order to induce the matter and anti-matter asymmetry observed in the Universe. The additional CP violation can be induced by complex vacuum, namely the spontaneous CP violation. In this paper we reveal the intimate connection of the spontaneous CP violation and the lightness of the Higgs boson, which was recently discovered by ATLAS and CMS at the LHC.
