Abstract

We study the production of hyperon resonances in the ppˉΛˉΣηp\bar{p}\to\bar{\Lambda}\Sigma\eta reaction within an effective Lagrangian approach. The model includes the production of Σ(1750)\Sigma(1750) and Λ(1670)\Lambda(1670) in the intermediate state excited by the KK and KK^* meson exchanges between the initial proton and antiproton. Due to the large coupling of Σ(1750)Ση\Sigma(1750)\Sigma\eta vertex, Σ(1750)\Sigma(1750) is found a significant contribution near the threshold in this reaction. We provide total and differential cross section predictions for the reation and discuss the possible influence of Σ(1750)Ση\Sigma(1750)\Sigma\eta vertex coupling and model parameters, which will be useful in future experimental studies. This reaction can provide a platform for studying the features of Σ(1750)\Sigma(1750) resonance, especially the coupling to Ση\Sigma\eta channel.
