Configurational entropy and the N^*(1440) Roper resonance in QCD
read the original abstract
The electroexcitation of the ${\cal N}^*(1440)$ Roper resonance, which defines the first radially excited state of the nucleon, is examined within the soft-wall AdS/QCD model. Such excited Fock states are characterized by the leading three-quark component, which determines the main properties of Roper resonance. The differential configurational entropy (DCE) was used in the nuclear interaction with a gauge vector field for ${\cal N}^*(1440)$ transition. Comparing the main results with the recent data of the CLAS Collaboration at JLab shows a good agreement on the accuracy of the computed data.

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.
