Abstract :We investigate the behavior of light baryons in hot QCD. To this aim, we evaluate the light baryons mass and residue in hot medium using the thermal correlation function with two-point by means of the thermal QCD sum rule. In sum rule calculations, we consider the additional thermal condensates appearing in Wilson expansion at T≠0. We determine the thermal continuum threshold using obtained sum rules expressions to analyze numerically. We observe that the masses and residues of light baryons stay approximately the same until the temperature reaches a certain value and then they fall with the temperature increase. We see that vacuum values of parameters in our calculations are in good consistency with other studies in the literature. Also, we define the fit functions that show how the spectroscopic parameters for light baryons behave at T≠0.
