摘要
研究几个0自旋c介子衰变过程中OZI规则的破坏效应,在含有中间虚介子的两次作用过程中,通过中间态计算其衰变分支比,结果表明,在相关衰变过程中对OZI规则的破坏不同,其中ηc介子对OZI规则的破坏最大.
OZI rule violations were investigated in the decay of c5 mesons with spin 0, and gave an estimate of the Contributions from intermediate states to the decay branching ratios. OZI rule violations in those mesons decay processes were discussed. The calculation results for those decay were compared with the experimental observations, which show there are different OZI rule violations in those decay processes.
