Abstract

By analyzing data samples of 2.9fb1 collected at s=3.773GeV, 482pb1 collected at s=4.009GeV and 67pb1 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, ΞΞ¯+ and Ξ0Ξ¯0 decays. None are observed, and upper limits are set at the 90% confidence level.
