Informational entropic Regge trajectories of meson families in AdS/QCD

Bulk mesons propagating in chiral and gluon condensates, in a gravitational background, are scrutinized in holographic soft wall AdS/QCD models, involving deformed dilatonic backgrounds. The configurational entropy of the a₁ axial vector, the ρ vector, and the f₀ scalar meson families is then computed. Two types of informational entropic Regge trajectories are then obtained, where the logarithm of the meson configurational entropy is expressed in terms of both the experimental meson mass spectra and their excitation number as well. Therefore, the mass spectra of the next generation of elements in each meson family, besides being predicted as eigenvalues of Schrödinger-like equations, are estimated with better accuracy and are discussed.
