Abstract
The standard model (SM) has several issues related to the violation which could give clues to search physics beyond the SM. They are a phase in the CKM matrix, the strong problem, phases in the PMNS matrix and asymmetry in lepton number violating processes related to baryon number asymmetry. We consider a model which could give a unified explanation for them in a framework of spontaneous violation. It is an extension of the SM with vector-like fermions and singlet scalars. In this model, they are explained by a common complex phase caused in the spontaneous violation. We present concrete examples for them and also discuss some relevant phenomenology.
