Newly observed $κ$(2600) and the highly excited states of $K_0^{*}$ family

Abstract: We conducted a study using the modified Godfrey-Isgur (MGI) quark model and quark pair creation model (QPC model) to investigate the spectrum and two body strong decays of the newly discovered $\kappa$(2600) meson in LHCb collaboration. Our analysis revealed that this resonant can be assigned as the fourth radial excitation within the $0^{+}$ light strange meson family. Furthermore, we predicted additional radial excitations in this meson family and systematically discussed their spectra, decay behaviors, and branching ratios. These results provide critical guidance for future to identify their signatures in experiments
