| 英文摘要 | 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 compatible with lund and shandong phenomenological models, based on the experimental results, the strangeness suppression factor s/u and spin suppression factor v(v + p) can be calculated to be similar to 0.3 and similar to 0.3-0.5, respectively, which are in goad agreement with those given by the argus collaboration in the upsilon region. this indicates that the su(6) breaking is consistent in the energy region from j/psi to upsilon. |
