QCD determination of the axial-vector coupling of the nucleon at finite temperature

C. A. Dominguez, M. Loewe, C. van Gend

A thermal QCD Finite Energy Sum Rule (FESR) is used to obtain the temperature dependence of the axial-vector coupling of the nucleon, $g_A(T)$. We find that $g_A(T)$ is essenti…
