Nucleons and higher spin baryon resonances: An AdS/QCD configurational entropic incursion

Luiz F. Ferreira (Federal University of ABC, Center of Mathematics, 09580-210 Santo André, Brazil; Federal University of ABC, Center of Physics, 09580-210 Santo André, Brazil) ; Roldao da Rocha (Federal University of ABC, Center of Mathematics, 09580-210 Santo André, Brazil)

Families of JP=12+ nucleons (N(939), N(1440), N(1710), N(1880), N(2100), N(2300)) and JP=32 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 JP 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 JP 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.
