Abstract: (APS)

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 ΛΛ¯π+π-, ΛΛ¯π0, ΛΛ¯η, Σ+Σ¯-, Σ0Σ¯0, Ξ-Ξ¯+ and Ξ0Ξ¯0 decays. None are observed, and upper limits are set at the 90% confidence level.
