N2 - Using e+e− collision data corresponding to a total integrated luminosity of 20 fb−1 collected with the BESIII detector at the BEPCII collider, we present a measurement of the Born cross section for the process e+e−→pK−K−Ξ¯+ at 39 center-of-mass energies between 3.5 and 4.9 GeV with a partial reconstruction technique. By performing a fit to the dressed cross section of e+e−→pK−K−Ξ¯+ with a power law function for continuum production and one resonance at a time for the ψ(3770), ψ(4040), ψ(4160), ψ(4230), ψ(4360), ψ(4415) or ψ(4660), respectively, the upper limits for the product of partial electronic width and branching fraction into the final state pK−K−Ξ¯+ for these resonances are determined at the 90% confidence level.
