Özet
Using 448.1 x 10(6) psi(3686) decays collected with the BESIII detector at the BEPCII e(+)e(-) storage rings, the branching fractions and angular distributions of the decays chi(cJ) -> Xi(-)(Xi) over bar (+) and Xi(0)(Xi) over bar (0) ( J = 0, 1, 2) are measured based on a partial-reconstruction technique. The decays chi(c1) -> Xi(0)(Xi) over bar (0) and chi(c2) -> Xi(0)(Xi) over bar (0) are observed for the first time with statistical significances of 7 sigma and 15 sigma, respectively. The results of this analysis are in good agreement with previous measurements and have significantly improved precision.
