$\mathbf{SU}(3{)}_{\mathbf{C}}\otimes \mathbf{SU}(3{)}_{\mathbf{L}}\otimes \mathbf{U}(1{)}_{\mathbf{X}}$ models in view of the $750$ GeV diphoton signal

Abstract

We analyze the recent diphoton signal reported by ATLAS and CMS collaborations in the context of the $SU(3{)}_C\otimes SU(3{)}_L\otimes U(1{)}_X$ anomaly free models, with a 750 GeV scalar candidate which can decay into two photons. These models may explain the 750GeV signal by means of one loop decays to $\gamma \gamma$ through charged vector and Higgs bosons, as well as top-, bottom- and electron-like exotic particles that arise naturally from the condition of anomaly cancellations of the $SU(3{)}_C\otimes SU(3{)}_L\otimes U(1{)}_X$ models.
