Abstract
The meson family of η pseudoscalars is studied in the context of the AdS/QCD correspondence and the differential configurational entropy (DCE). For it, two forms of configurational-entropic Regge-like trajectories are engendered, relating the η mesonic states excitation number to both their experimental mass spectrum in the Particle Data Group (PDG) and the DCE as well. Hence, the mass spectrum of η pseudoscalar mesonic states, beyond the already detected states η(550), η(1295), η(1405), η(1475), η(1760), η(2225), and η(2320), is derived for any excitation number. The three first ulterior members of this family are then analyzed and also compared to existing candidates in PDG.
