Entropic information of dynamical AdS/QCD holographic models

TL;DR

This paper explores how Shannon-based conditional entropy in dynamical holographic AdS/QCD models helps classify mesons and understand their stability, linking information theory with particle physics.

Contribution

It introduces a novel application of Shannon entropy to holographic QCD models, providing insights into meson classification and stability analysis.

Findings

Conditional entropy correlates with meson spin and stability.

Higher spin mesons have higher entropy and are less stable.

Entropy analysis supports experimental meson classification schemes.

Abstract

The Shannon based conditional entropy that underlies five-dimensional Einstein-Hilbert gravity coupled to a dilaton field is investigated in the context of dynamical holographic AdS/QCD models. Considering the UV and IR dominance limits of such AdS/QCD models, the conditional entropy is shown to shed some light onto the meson classification schemes, which corroborate with the existence of light-flavour mesons of lower spins in Nature. Our analysis is supported by a correspondence between statistical mechanics and information entropy which establishes the physical grounds to the Shannon information entropy, also in the context of statistical mechanics, and provides some specificities for accurately extending the entropic discussion to continuous modes of physical systems. From entropic informational grounds, the conditional entropy allows one to identify the lower experimental/phenomenological occurrence of higher spin mesons in Nature. Moreover, it introduces a quantitative theoretical apparatus for studying the instability of high spin light-flavour mesons.
