Dependence of Nsig on the effective coupling constants gggX and gcc¯X at a combination of the luminosity of s=7,8 and 13 TeV LHC. The parameter space region above the red line is excluded by the experimental constraint of Γ[X(6900)gg]+Γ[X(6900)cc¯]<Γ[X(6900)all]168 MeV. The black lines stand for the experimental constraint given by the yield of Nsig=784±148.
Di-J/ψ invariant mass distribution of cross sections (upper) and event numbers (lower) for both signal and SM background for ppJ/ψJ/ψ4μ at the benchmark point B. S and S^ represent the new physics signals induced by X(6900) with and without interference effect, respectively.
