摘要:

研究J/Ψ介子衰变过程对OZI规则的破坏效应, 通过中间态K*K和ρπ计算其衰变分支比的贡献.  结果表明, J/Ψ→f0衰变过程的理论结果和实验结果相符, 即在该过程中对OZI规则的破坏较大. 

关键词: OZI规则, 中间虚介子, 衰变, 分支比

Abstract:

OZI rule violations were investigated in the decay of  J/Ψ mesons, and an estimate of the contributions from intermediate states to the decay branching ratios was given.  OZI rule violations in the  J/Ψ  meson decay processes were discussed. The calculation results for  J/Ψ→f0 decay are in agreement  with the experimental results, which shows there are large OZI rule violations in those decay processes.

Key words: OZI rule, intermediate virtual mesons, decay, branching ratio
