| 英文摘要 | Using a data sample of (448.1 +/- 2.9) x 10(6) psi (3686) events collected with the besiii detector at the bepcii collider, we present measurements of branching fractions for the decays x-cj -> sigma(+) (sigma) over bar (-) and sigma(0) (sigma) over bar (0) the decays x-c1.2 -> sigma(+) (sigma) over bar (-) and sigma (sigma) over bar (0) are observed for the first time, and the branching fractions for x-c0 -> sigma(+) (sigma) over bar (-) and sigma(0) (sigma) over bar (0) decays are measured with improved precision. the branching fraction ratios between the charged and neutral modes are consistent with the prediction of isospin symmetry. |
