Resumo

The meson family of eta 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 eta 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 eta pseudoscalar mesonic states, beyond the already detected states eta(550), eta(1295), eta(1405), eta(1475), eta(1760), eta(2225), and eta(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. (C) 2021 The Author. Published by Elsevier B.V. (AU)
