摘要
考虑各种相关性,估算出ψ’与J/ψ之间非粲强衰变的比值Q为(26.0±3.5)%.在估算过程中,为了获得相关系数或方差,采用了多种方法.这些方法在数据的相关性分析中具有实际的应用价值.
Q value, the ratio of charmless hadronic decays between ψ＇ and J/ψ, is evaluated to be （26.0±3.5）%. In the evaluation of Q value, the correlations due to measured variable transformation and experimental common error have been taken into account carefully, and several approaches are adopted to find out the correlation coefficient or covariance between different measurements.
