Description
Studies into baryon-meson interactions reveal significant insights into quantum chromodynamcis (QCD) at hadronic scales, forming a critical foundation for advancing hadron spectroscopy. We calculate the effective potentials of octet baryon and heavy meson systems using the chiral effective field theory up to the next-to-leading order. The low energy constants (LECs) are correlated with those of the \bar{N}N interaction using a quark-level Lagrangian approach. Our research provides new insights into several near-threshold charmed baryons [e.g., \Lambda_{c}(2940), \Xi_{c}(3055), and \Omega_{c}(3188), etc.] around 3 GeV from the hadronic molecular perspective. We also identify several molecular states, designated as \Xi_{c}, within the mass range of 3100-3500 MeV.
