| dc.description | A sample of 3.95M $ψ(2S)$ decays registered in the BES detector are used to study final states containing pairs of octet and decuplet baryons. We report branching fractions for $ψ(2S)\to p\bar{p}$, $Λ\barΛ$, $Σ^0\barΣ{}^0$, $Ξ^-\barΞ{}^+$, $Δ^{++}\barΔ{}^{--}$, $Σ^+(1385)\barΣ{}^-(1385)$, $Ξ^0(1530)\barΞ{}^0(1530)$, and $Ω^-\barΩ{}^+$. These results are compared to expectations based on the SU(3)-flavor symmetry, factorization, and perturbative QCD. | |
