- 論文の詳細を見る
The decay widths Γ(J/ψ→qq^^-),Γ(η_c→qq^^-) and Γ(η_c'→qq^^-) are re-examined. By using the results, the cross sections for hadronic production of η_c(η_Q) or η_c'(η_Q') are predicted on the basis of the model of quark-antiquark as well as gluon-gluon fusion, and the ratio of σ(h+h→η_c'→J/ψ+γ) to σ(h+h→x_c→J/ψ+γ) is estimated. It is pointed out that the study of hadronic production of η_c(η_c') is one of the best means to see which is the most suitable among the models suggested by several authors in order to explain the data for J/ψ production in p^^--N and p-N collisions.
