| 英文摘要 | The discovery of a light Higgs particle h(0) (125 GeV) opens up new prospect for searching heavier Higgs boson(s) at the LHC Run-2, which will unambiguously point to new physics beyond the standard model (SM). We study the detection of a heavier neutral Higgs boson H-0 via di-Higgs production channel at the LHC (14TeV), H-0 -> h(0)h(0) -> WW*gamma gamma. This directly probes the Hhhcubic Higgs interaction, which exists in most extensions of the SM Higgs sector. For the decay products of final states WW*, we include both pure leptonic mode WW* -> l (nu) over barl (nu) over bar and semi-leptonic mode WW* -> q (q) over bar 'l nu. We analyze signals and backgrounds by performing fast detector simulation for the full process pp -> H -> hh -> WW*gamma gamma -> l (nu) over bar(l) over bar gamma gamma and pp -> H -> hh -> WW*gamma gamma -> l nu q (q) over bar'gamma gamma, over the mass range M-H = 250-600 GeV. For generic two-Higgs-doublet models (2HDM), we present the discovery reach of the heavier Higgs boson at the LHC Run-2, and compare it with the current Higgs global fit of the 2HDM parameter space.
