| contents | We study the production of hyperon resonances in the $p\bar{p}\to\barΛΣη$ reaction within an effective Lagrangian approach. The model includes the production of $Σ(1750)$ and $Λ(1670)$ in the intermediate state excited by the $K$ and $K^*$ meson exchanges between the initial proton and antiproton. Due to the large coupling of $Σ(1750)Ση$ vertex, $Σ(1750)$ 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 $Σ(1750)Ση$ vertex coupling and model parameters, which will be useful in future experimental studies. This reaction can provide a platform for studying the features of $Σ(1750)$ resonance, especially the coupling to $Ση$ channel. |
