Effective Couplings between Two Photons and Axion in the 3-3-1 Model

Hoang Ngoc Long, Vo Van Vien, Vu Hoa Binh

Abstract: The one-loop contribution axion-photon-photon coupling is presented in the framework of the 3-3-1 model, in which the loop diagrams are finite. The decay of axion into two photons is demonstrated. This study shows that it is easy to fulfill dark matter candidate conditions for the axion in the model. Keywords: extensions of electroweak gauge sector, extensions of electroweak Higgs sector, Electroweak radiative correction
