Baryon number is an accidental symmetry in the standard model, while Peccei-Quinn hypothetical which introduced to solve strong $CP$ problem. We study possible connections between and baryon symmetry. In this framework, axion identified as Nambu-Goldstone boson of violation. As a result, characteristic violating processes are predicted. developed general method determine lepton new scalar model.
