Information from each Monte Carlo simulated decay event is used to construct matrices connecting the detected distributions to the input predetection {"}produced{"}distributions. Assuming these matrices also apply to data, they are used to predict the analogous produced distributions of the decay events. Using these, the charged particle multiplicities are compared with results from MARK I. Further, comparison of the distributions of the number of photons in data with those in Monte Carlo simulation indicates that G-parity conservation should be taken into consideration in the simulation.",

N2 - Using a sample of 106 million ψ(3686) decays, ψ(3686)→γχcJ(J=0,1,2) and ψ(3686)→γχcJ,χcJ→γJ/ψ(J=1,2) events are utilized to study inclusive χcJ→anything, χcJ→hadrons, and J/ψ→anything distributions, including distributions of the number of charged tracks, electromagnetic calorimeter showers, and π0s, and to compare them with distributions obtained from the BESIII Monte Carlo simulation. Information from each Monte Carlo simulated decay event is used to construct matrices connecting the detected distributions to the input predetection "produced"distributions. Assuming these matrices also apply to data, they are used to predict the analogous produced distributions of the decay events. Using these, the charged particle multiplicities are compared with results from MARK I. Further, comparison of the distributions of the number of photons in data with those in Monte Carlo simulation indicates that G-parity conservation should be taken into consideration in the simulation.
