Higher excitation states are matched with Particle Data Group candidates.

The approach provides insights into meson structure and excitation levels.

Abstract

The mass spectra of isovector $\Upsilon$, $\psi$, $\phi$, and $\omega$ meson resonances are investigated, in the AdS/QCD and information entropy setups. The differential configurational entropy is employed to obtain the mass spectra of radial $S$-wave resonances, with higher excitation levels, in each one of these meson families, whose respective first undisclosed states are discussed and matched up to candidates in the Particle Data Group.
