Three-channel separable potential analysis of PccÌ…s(4338)
Abstract
The recently discovered hidden-charm pentaquark Pcc̅s(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 ΞcD̅ 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 Pcc̅s(4338) between the Ξc0D̅0 and Ξc+D̅− thresholds.
