The feasibility of a measurement of the partial decay width of the intermediate-mass Higgs boson(MH=120 GeV ) into two photons at a photon-photon collider is studied by a simulation. It is found that the two-photon decay width can be measured with the statistical error of 7.6% with the integrated luminosity of 10fb-1. We also discussed a possibility toward further improvement with sophisticated b-quark tagging technique.

AbstractThe two-photon decay widths of scalar mesons σ(600), f 0(980) and a 0(980) as well a 0 → ju(ω)γ and f 0 → ju(ω)γ are calculated in the framework of the local Nambu-Jona-Lasinio model. The contributions of the quark loops (Hartree-Fock approximation) and the meson loops (next 1/N c-approximation where N c is the number of colors) are taken into account. The values of these contributions, as we show, are of the same order of magnitude. For the f 0 decay the K-loop contribution plays the dominant role. The results for two-gamma decays are in satisfactory agreement with modern experimental data. The predictions for a 0 → ju(ω)γ and f 0 → ju(ω)γ widths are given.

Abstract We have corrected the decay width for the two photon decay widths for scalar and pseudo-scalar Charmonium in [Chinese Physics C Vol.44,No.8(2020)083108]. The decay widths are now in better agreement with the experiment values.
