Spectroscopy of charmonium-like mesons, heavy-light mesons with charm, AdS/QCD, and configurational entropy

Abstract

Heavy-light-flavor meson resonances with charm, in the $D^0$ and $D^{\ast }$ families, and charmonium-like states, in the ${\eta }_c$ and ${\chi }_{c1}$ families, are explored and discussed in the AdS/QCD model with four quark flavors. The differential configurational entropy is computed and analyzed for these four charmed meson families, also combining 4-flavor AdS/QCD to experimental data for the $D^0$, $D^{\ast }$, ${\eta }_c$, and ${\chi }_{c1}$ meson families. It makes it possible to predict the mass spectrum of unexplored heavier charmed meson resonances and to identify further charmed meson states reported in PDG.
