![The study demonstrates that nucleon effective mass, extracted from two-point correlators, aligns with relativistic expectations-specifically, [latex]m\_{\rm eff}=\sqrt{m\_{0}^{2}+(P^{z})^{2}}[/latex] with a static mass of 1.1 GeV-and that a fit to the ground-state energy dispersion relation-[latex]E=\sqrt{m\_{0}^{2}+c\_{1}P^{2}+c\_{2}a^{2}P^{4}}[/latex]-accurately captures the momentum dependence of nucleon energies, as evidenced by the consistency between fitted parameters and theoretical predictions.](https://arxiv.org/html/2602.11283v1/x2.png)
