Correlation in estimation of the Q value
Description
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.
