A holographic bottom-up approach to Sigma baryons
read the original abstract
In this work, we discuss the description of neutral $\Sigma$ baryons with $I(J^P)=1(1/2^+)$ and $I(J^P)=1(3/2^+)$ using two bottom-up approaches: the deformed background and the static dilaton. In both models, we consider a non-linear Regge trajectory extension motivated by the \emph{strange} nature that $\Sigma$ baryons have. We found that both models describe these systems with an RMS error smaller than 10 $\%$. We also perform a configurational entropy calculation in both models to discuss hadronic stability.

Nucleon spectra and wave functions from holographic models with dual Einstein-dilaton and Starobinsky-dilaton gravities
Adding a fitted λ parameter and Starobinsky αR² corrections lets holographic Einstein-dilaton models reproduce the nucleon radial-excitation spectrum with errors as low as 0.29%.

Thermodynamics of the Isospectral family of holographic vector mesons
Isospectral transformations in softwall AdS/QCD allow tuning the rho meson's decay constant to its experimental value of 226 MeV, producing a predicted melting temperature of 157 MeV from spectral function computation...

Holographic information measures for spin-$3/2$ $\Delta$ baryons in AdS/QCD
Holographic AdS/QCD calculations of configurational entropy and complexity for Delta baryons yield Regge trajectories that organize known masses and predict additional resonances.

Digit anomalies in the hadronic mass spectrum, classical and quantum information entropies, and the dynamical QCD scale
The first digits of PDG hadron masses deviate strongly from Benford's law, and the paper reads the resulting Shannon-entropy deficit as a signature of Lambda_QCD.
