摘要Recently, an excess of events in diphoton channel with invariant mass of about 750 GeV has been reported by the ATLAS and CMS Collaborations. Considering it as a tantalizing hint for new physics beyond the Standard Model (SM), we propose a simple extension of the SM with an additional doublet Higgs H' and a singlet s. We consider the neutral component H-0' of H' as the 750 GeV resonance and assume that s is lighter than 2.6 GeV. In particular, H-0' can be produced at tree level via q (q) over bar production and decay into a pair of s at tree level. Then s can decay into a pair of collimated photons, which cannot be distinguished at the LHC. We show that the diphoton production cross section can be from 3 to 13 fb, the decay width of H-0' can be from 30 to 60 GeV, and all the current experimental constraints including dijet constraint can be satisfied.
