# Tensor mesons, AdS/QCD and information

## TL;DR

This paper combines AdS/QCD and information theory to analyze tensor meson resonances, deriving configurational-entropic Regge trajectories that relate meson spin, entropy, and mass spectra, and compares results with experimental data.

## Contribution

It introduces a hybrid approach using information theory within AdS/QCD to study higher spin tensor mesons and derive new configurational-entropic Regge trajectories.

## Key findings

- Mass spectra of tensor mesons match experimental data.
- Configurational entropy correlates with meson spin and mass.
- New insights into meson resonance structure and spectra.

## Abstract

The Kaluza-Klein tower of higher spin-$S$ tensor meson resonances is here scrutinized in the AdS/QCD hard wall model, encompassing the already established resonances $\rho(770)$, $f_2(1270)$, $\omega_3(1670)$, $f_4(2050)$, $\rho_5(2350)$, $f_6(2510)$ in PDG. A hybrid model employs both information theory and AdS/QCD, where configurational-entropic Regge trajectories, relating the configurational entropy of the tensor mesons family to their $S$ spin, and also to their experimental mass spectra, are derived and analyzed. Therefore, the mass spectra of higher spin-$S$ tensor meson resonances is obtained and compared to the existing data in PDG.
