HIGGS SECTOR IN THE 3-3-1 MODEL WITH AXION DARK MATTER

Abstract

The Higgs sector in the 3-3-1 model with axion dark matter is presented. The diagonal- ization of 4 × 4 square mass matrix for the CP-odd sector is exactly fulfilled.
Our results show that the axion is mainly contained from the CP-odd part of the singlet φ, while the CP-even component of the later is the inflaton of the model. The positivity of the masses leads to constraints for some couplings of the Higgs sector. PACS numbers: 11.30.Fs, 12.15.Ff, 12.60.-i
