Mass of the nucleon ground state N+ and its parity partner N−, normalized to the N+ mass, as function of normalized temperature for μB = 0 and isospin symmetric matter. We compare results from the QχP model with lattice QCD data (Aarts et al. 2017). For comparison, we also include QχP results (green, dashed line), where N− is normalized by the lattice QCD nucleon mass, which in the cited study is still unphysically large.
