Abstract
We study the resonance with in the context of the pentaquark hypothesis in the nuclear medium. For the investigation of the influence of the nuclear medium on the physical parameters of , we propose a molecular-type structure involving and admixtures, correlated with the nuclear matter density. Our analysis reveals a substantial shift in both mass and residue, approximately and , respectively. These findings have significant implications for experimental researchers aimed at identifying in-medium characteristics of hyperon resonances.
