| 英文摘要 | We generalize the quark-pair creation model to a study of the radiative decays J/Psi-->gammaB (B) over bar by assuming that the u, d, or s quark pairs are created with the same interaction strength. From the calculation of the ratio of the decay widths Gamma(J/Psi-->gammap (p) over bar)/Gamma(J/Psi-->p (p) over bar), we extract the quark-pair creation strength g(I) = 15.40 GeV. Based on the SU(6) spin-flavour basis and the "uds" basis, the radiative decay branching ratios containing strange baryons are evaluated. Measurements for these decay widths from the BESII data are suggested. |
