Restoration of singlet axial symmetry at finite temperature
To accommodate recent RHIC data on eta' multiplicity, we propose a minimal modification of the Witten–Veneziano relation at high temperature. This renders a significant drop of eta' mass at high temperature signaling a restoration of the U(1)_A, and the Goldstone character of eta'.
