Abstract
The mean multiplicities of mesons pi(+/-), pi(0), K+/-, K-S(0), rho(0) , K(0), M*(+/-), and phi and baryons p, Xi(+/-), and Sigma(+/-) (1385 ) are measured for the first time at J/psi region with 200,000 events collected at the BEPC with the BES detector. The results are compatibl e with LUND and Shandong phenomenological models, Based on the experim ental results, the strangeness suppression factor s/u and spin suppres sion factor V(V + P) can be calculated to be similar to 0.3 and simila r to 0.3-0.5, respectively, which are in goad agreement with those giv en by the ARGUS Collaboration in the Upsilon region. This indicates th at the SU(6) breaking is consistent in the energy region from J/psi to Upsilon.
