| contents | Within the heavy pentaquark chiral perturbation theory, we calculate the chiral corrections for $J^P=\frac{3}{2}^-$ octet hidden-charm pentaquark masses up to next-to-leading order. Taking the LHCb-reported $P_ψ^N(4440)$ and $P_{ψs}^Λ(4459)$ (with $J^P=\frac{3}{2}^-$) as inputs, we predict the other two octet hidden-charm pentaquark states $P_{ψs}^Σ(4483)$ and $P_{ψss}^{N}(4490)$ with $J^P=\frac{3}{2}^-$. The results provide theoretical guidance for the further search of $P_{ψs}^Σ$ and $P_{ψss}^{N}$ in experiments. |
