Search for baryonic decays of ψ(3770) and ψ(4040)
By analyzing data samples of 2.9 fb-1 collected at √s=3.773 GeV, 482 pb-1 collected at √s=4.009 GeV and 67 pb-1 collected at √s=3.542, 3.554, 3.561, 3.600 and 3.650 GeV with the BESIII detector at the BEPCII storage ring, we search for ψ(3770) and ψ(4040) decay to baryonic final states, including ΛΛ̄ π+π-, ΛΛ̄π0, ΛΛ̄η, Σ+Σ̄ -, Σ0Σ̄0, Ξ -Ξ̄+ and Ξ0Ξ̄0 decays. None are observed, and upper limits are set at the 90% confidence level. © 2013 American Physical Society.
