dc.description.abstractUsing a data sample of (1.0087 +/- 0.0044) x 10(10) J/psi decay events collected with the BESIII detector at the center-of-mass energy of root s = 3.097 GeV, we present a search for the hyperon semileptonic decay Xi(0) -> Sigma(-)e(+)nu(e) which violates the Delta S = Delta Q rule. No significant signal is observed, and the upper limit on the branching fraction B(Xi(0) -> Sigma(-)e(+)nu(e)) is determined to be 1.6 x 10(-4) at the 90% confidence level. This result improves the previous upper limit result by about one order of magnitude.en_US
