Charmonium results from BES

  • Using ~14×106 ψ(2S) and ~58×106 J/ψ data collected at BESⅡ/BEPC, the branching fraction of ψ(2S)→ΩΩ+ is measured with about 5σ statistical significance. The Λ electric dipole and Λ decay parameter are studied using the decay J/ψ→ΛΛ→pp π+π. Using (106±3)×106 ψ(2S) decays collected at BESⅢ/BEPCⅡ, we have obtained some interesting physics results. The branching fractions of χcj→π0π0, ηη are measured with precision improved. The mass and width of hc(11P1) state, together with the branching fractions of Br(ψ(2S)→π0hc) and Br(hc→γηc) are the first measurements. Surprisingly, the decays of χc1→φφ, ωω, and ωφ are firstly observed in BESⅢ data.

Charmonium results from BES

  • Institute of High Energy Physics, Chinese Academy of Sciences, Beijing 100049, China

Abstract: 

Using ~14×106 ψ(2S) and ~58×106 J/ψ data collected at BESⅡ/BEPC, the branching fraction of ψ(2S)→ΩΩ+ is measured with about 5σ statistical significance. The Λ electric dipole and Λ decay parameter are studied using the decay J/ψ→ΛΛ→pp π+π. Using (106±3)×106 ψ(2S) decays collected at BESⅢ/BEPCⅡ, we have obtained some interesting physics results. The branching fractions of χcj→π0π0, ηη are measured with precision improved. The mass and width of hc(11P1) state, together with the branching fractions of Br(ψ(2S)→π0hc) and Br(hc→γηc) are the first measurements. Surprisingly, the decays of χc1→φφ, ωω, and ωφ are firstly observed in BESⅢ data.
