| Abstract: | We interpret the potential observation of the 750 GeV di-photon resonance at the LHC in models, in which an SU(2) isospin-singlet scalar boson mixes with the Standard Model (SM) Higgs boson through an angle $\alpha$. Allowing the singlet scalar boson to have renormalizable couplings to vector-like leptons and quarks, we can explain the large production cross section $\sigma(H_2) \times B(H_2 \to \gamma \gamma)$ as well as the apparent large total width of the boson without conflicts from the results obtained by previous global ts to the SM Higgs boson data. |
