英文摘要	From J/psi-->p (p) over bar, Lambda(&ULambda;) over bar, Sigma(0)(&USigma;) over bar (0), and Xi(+)Xi(-) decays we study the structure of baryons including nucleons, Lambda, Sigma, and Xi in the naive quark model. Considering the lowest-order quark diagrams for baryon-antibaryon pair production from J/psi decays we calculate the baryon-antibaryon angular distributions. Using the experimental data for the angular distribution for the process J/psi-->p (p) over bar produced in e(+)-e(-) collisions, we determine the range of parameters for the quark mass m(q) and the harmonic-oscillator parameter beta in the quark model. With these parameters, we calculate the branching fractions and angular distributions for the above J/psi decay processes and find that the calculated values are comparable with the measured ones.
