Higher-spin light-flavor baryonic spectroscopy in AdS/QCD at finite temperature

Abstract

Light-flavor baryon resonances in the $J^P=3/2^{+}$, $J^P=5/2^{+}$, and $J^P=5/2^{-}$ families are investigated in a soft-wall AdS/QCD model at finite temperature, including the zero temperature limit. Regge-like trajectories relating the configurational entropy underlying these resonances to both the radial quantum number and the baryon mass spectra are constructed, allowing for the extrapolation of the higher-spin light-flavor baryonic mass spectra to higher values of the radial quantum number. The configurational entropy is shown to increase drastically with temperature, in the range beyond T ~ 38 MeV. The mass spectra of baryon families are analyzed, supporting a phase transition nearly above the Hagedorn
