Abstract

Strange axial-vector kaons, K1, and f1 meson resonances are investigated in the 4-flavor AdS/QCD model. Their underlying differential configurational entropy is computed and the mass spectra of higher-excited resonances, in both these mesonic families, are achieved and discussed. This technique merges the 4flavor AdS/QCD and experimental data regarding the mass spectrum of K1 and f1 meson resonances that have been already detected and reported in the Particle Data Group, also bringing forth a route to explore physical features of the next generation of resonances in the K1 and f1 meson families.
