Title: Observation of ψ ( 3686 ) Ξ ( 1530 ) Ξ ¯ ( 1530 ) + and Ξ ( 1530 ) Ξ ¯ +

Abstract

Using 448.1 × 106 ψ(3686) events collected with the BESIII detector at BEPCII, we employ a single-baryon tagging technique to make the first observation of ψ(3686) → Ξ(1530) Ξ¯(1530)+ and Ξ(1530) Ξ¯+ decays with a statistical significance of more than 10σ and 5.0σ, respectively. The branching fractions are measured to be B(ψ(3686) → Ξ(1530) Ξ¯ (1530)+) = (11.45 ± 0.40 ± 0.59) × 105 and B(ψ(3686) → Ξ(1530)Ξ¯+) = (0.70 ± 0.11 ± 0.04) × 10–5. The angular distribution parameter for ψ(3686) → Ξ(1530) Ξ¯(1530)+ is determined to be α = 0.40 ± 0.24 ± 0.06, which agrees with the theoretical predictions within 1σ. The first uncertainties are statistical, and the second systematic.

abstractNote = {Using 448.1 × 106 ψ(3686) events collected with the BESIII detector at BEPCII, we employ a single-baryon tagging technique to make the first observation of ψ(3686) → Ξ(1530)– Ξ¯(1530)+ and Ξ(1530)– Ξ¯+ decays with a statistical significance of more than 10σ and 5.0σ, respectively. The branching fractions are measured to be B(ψ(3686) → Ξ(1530)– Ξ¯ (1530)+) = (11.45 ± 0.40 ± 0.59) × 105 and B(ψ(3686) → Ξ(1530)–Ξ¯+) = (0.70 ± 0.11 ± 0.04) × 10–5. The angular distribution parameter for ψ(3686) → Ξ(1530)– Ξ¯(1530)+ is determined to be α = 0.40 ± 0.24 ± 0.06, which agrees with the theoretical predictions within 1σ. The first uncertainties are statistical, and the second systematic.},
