| Abstract: | This analysis is based on 106 M ψ(2S) data collected with Beijing Spectrom- eter III (BESIII) detector at Beijing Electron Positron Collider II. We report improved measurements of the branching fractions of ψ(2S) → ΛΛπ + π − , + ∗− ψ(2S) → Ξ− Ξ and ψ(2S) → Σ∗+ Σ . The branching fractions measured are (1.34 ± 0.05stat ± 0.24sys ) × 10−4 , (3.15 ± 0.35stat ± 0.55sys ) × 10−5 and (3.39 ± 0.34stat ± 0.61sys ) × 10−5 , respectively. |
