Three-channel separable potential analysis of Pcc̅s(4338)

Abstract

The recently discovered hidden-charm pentaquark P_cc̅s(4338) state with strange quark content has sparked a new interest in the hadron physics community due to its ambiguous nature. This enhancement is observed above the relevant meson-baryon Ξ_cD̅ thresholds, leading to different competing interpretations. In this work, we used a three-channel separable potential model to consider different pole configurations such as a bound state and a virtual state pole in the coupled-channel formalism. Implementing such models, we have produced the line shapes of the scattering amplitudes for P_cc̅s(4338) between the Ξ_c⁰D̅⁰ and Ξ_c⁺D̅⁻ thresholds.
