Analysis of 𝚵(1620) resonance with chiral unitary approach

Abstract

Abstract. Recently, the ξ(1620) resonance has attracted much attention, thanks to detailed experimental data by the Belle and ALICE collaborations. This experimental progress has prepared us to conduct theoretical analyses based on experimental data. In this study, we analyze the ξ(1620) resonance using the chiral unitary model and discuss the properties of the ξ(1620) resonance and the K−Λ scattering length.
