Experimental Study of f0 (975) in the J/ψ Decays

  • Based on 7.8×106 J/ψ events collected by the BES at BEPC, through study of the hadronic decays J/ψ→φπ+π and J/ψ→ωπ+π, the branching ratios of the processes and the mass positions and the widths of f0 are obtained. The angular distributions of J/ψ→φf0,f0→π+π, are fitted and the helicity amplitude ratio of this process is first given.

Experimental Study of f0 (975) in the J/ψ Decays

  • Institute of High Energy Physics, The Chinese Academy of Sciences, Beijing 100039

Abstract: Based on 7.8×106 J/ψ events collected by the BES at BEPC, through study of the hadronic decays J/ψ→φπ+π and J/ψ→ωπ+π, the branching ratios of the processes and the mass positions and the widths of f0 are obtained. The angular distributions of J/ψ→φf0,f0→π+π, are fitted and the helicity amplitude ratio of this process is first given.
