摘要：

Using 1310.6 x 10(6) J/psi and 448.1 x 10(6) psi(3686) events collected with the BESIII detector, the branching fractions of J/psi decays to Sigma(+)(Sigma) over bar (-) is measured to be (10.61 +/- 0.04 +/- 0.36) x 10(-4), which is significantly more precise than the current world average. The branching fractions of psi(3686) decays to Sigma(+)(Sigma) over bar (-) is measured to be (2.52 +/- 0.04 +/- 0.09) x 10(-4), which is consistent with the previous measurements. In addition, the ratio of beta(psi(3686) -> Sigma(+)(Sigma) over bar (-)) / beta(J/psi -> Sigma(+)(Sigma) over bar (-)) is determined to be (23.8 +/- 1.1)% which violates the "12% rule".
