Nucleons and higher spin baryon resonances: An AdS/QCD configurational entropic incursion
Luiz F. Ferreira, Roldão da Rocha
Abstract
Families of ${J}^{P}={\frac{1}{2}}^{+}$ nucleons ($N(939)$, $N(1440)$, $N(1710)$, $N(1880)$, $N(2100)$, $N(2300)$) and ${J}^{P}={\frac{3}{2}}^{\ensuremath{-}}$ nucleons ($N(1520)$, $N(1700)$, $N(1875)$, and $N(2120)$) are scrutinized from the point of view of the configurational entropy (CE). The mass spectra of higher ${J}^{P}$ resonances in each one of these families are then obtained when configurational-entropic Regge trajectories, that relate the CE of nucleon families to both their ${J}^{P}$ spin and also to their experimental mass spectra, are interpolated. The mass spectra of the next generation of nucleon resonances are then compared to already established baryonic states in particle data group (PDG). Besides the zero temperature case, the finite temperature analysis is also implemented.
