| dc.description.abstract | We study the decays of J/psi and psi(3686) to the final states Sigma(1385)(0)(Sigma) over bar (1385)(0) and Xi(0)(Xi) over bar (0) based on a single baryon tag method using data samples of (1310.6 +/- 7.0) x 10(6) J/psi and (447.9 +/- 2.9) x 10(6) psi(3686) events collected with the BESIII detector at the BEPCII collider. The decays to Sigma(1385)(0)(Sigma) over bar (1385)(0) are observed for the first time. The measured branching fractions of J/psi and psi(3686) to Xi(0)(Xi) over bar (0) are in good agreement with, and much more precise than, the previously published results. The angular parameters for these decays are also measured for the first time. The measured angular decay parameter for J/psi -> Sigma(1385)(0)(Sigma) over bar (1385)(0), alpha = -0.64 +/- 0.03 +/- 0.10, is found to be negative, different to the other decay processes in this measurement. In addition, the "12% rule" and isospin symmetry in the decays of J/psi and psi(3686) to Xi(Xi) over bar and Sigma(1385)(Sigma) over bar (1385) are tested. | en_US |
