Holographic information measures for spin-3/2 Δ baryons in AdS/QCD

Spin-3/2 Δ baryon resonances are investigated within AdS/QCD, using Rarita–Schwinger fields. The differential configurational entropy (DCE) and differential configurational complexity (DCC) associated with their bulk energy densities are computed. It yields Regge-like trajectories relating configurational information measures to the radial excitation number and the experimental mass spectrum of the Δ baryons. We then extrapolate the spectrum of heavier Δ baryon resonances beyond currently established states in the PDG, also comparing them with states in PDG omitted from the summary table. Our results support a relevant interplay among holographic QCD dynamics, configurational information entropy, and baryon spectroscopy in strongly coupled QCD.
