Muon anomalous magnetic moment and Higgs potential stability in the 331 model from SU(6)

Muon anomalous magnetic moment and Higgs potential stability in the 331 model from SU(6)

We consider a S U ( 3 ) c × S U ( 3 ) L × U ( 1 ) X model from a SU (6) Grand Unified Theory (GUT). In order to explain the anomalous magnetic moments of muon and electron, we introduce two new scalar triplets without vacuum expectation values (VEVs) so that the leading contributions to Δ a μ and Δ...

Zusammenfassung:We consider a S U ( 3 ) c × S U ( 3 ) L × U ( 1 ) X model from a SU (6) Grand Unified Theory (GUT). In order to explain the anomalous magnetic moments of muon and electron, we introduce two new scalar triplets without vacuum expectation values (VEVs) so that the leading contributions to Δ a μ and Δ a e can avoid the suppression from small muon mass. In addition, the Higgs potential stability of this 331 model is studied by giving a set of sufficient conditions to ensure the boundedness from below of the potential.
