Abstract

Close
- Using (448.1 +/- 2.9) x 10(6) psi (3686) events collected with the BESIII detector and a single-baryon tagging technique, we present the first observation of the decays psi(3686)-> Xi (1530)(0) (Xi) over bar (1530)(0) and Xi (1530)(0) (Xi) over bar (0). The branching fractions are measured to be B psi (3686)-> Xi (1530)(0) (Xi) over bar (1530)(0)) = (6.77 +/- 0.14 +/- 0.39 x 10(- 5) and B (psi(3686)-> Xi (1530)(0) (Xi) over bar (0) = (0.53 +/- 0.04 +/- 0.03) x 10(-5). Here, the first and second uncertainties are statistical and systematic, respectively. In addition, the parameter associated with the angular distribution for the decay psi (3686) ->Xi (1530)(0) (Xi) over bar (1530)(0) is determined to be alpha= 1/4 0.32 +/- 0.19 +/- 0.07, in agreement with theoretical predictions within one standard deviation.
