AbstractThe decays J/psi -> eta Sigma(+)(Sigma) over bar (-) and psi(3686) -> eta Sigma(+)(Sigma) over bar (-) are observed for the first time, using (10087 +/- 44) x 10(6) J/psi and (448.1 +/- 2.9) x 10(6) psi(3686) events collected with the BESIII detector at the BEPCII collider. We determine the branching fractions of these two decays to be B(J/psi -> eta Sigma(+)(Sigma) over bar (-)) = (6.34 +/- 0.21 +/- 0.37) x 10(-5) and B(psi(3686) -> eta Sigma(+)(Sigma) over bar (-)) = ( 9.59 +/- 2.37 +/- 0.61) x 10(-6), where the first uncertainties are statistical and the second are systematic. The ratio of these two branching fractions is determined to be B(psi(3686) -> eta Sigma(+)(Sigma) over bar (-))/B(J/psi -> eta Sigma(+)(Sigma) over bar (-)) = (15.1 +/- 3.8)%, which is in agreement with the 12% rule.
