1207.3068 (S. Benic et al.)

Restoration of singlet axial symmetry at finite temperature    [PDF]

S. Benic, D. Horvatic, D. Kekez, D. Klabucar
To accomodate recent RHIC data on eta prime multiplicity, we propose a minimal modification of the Witten-Veneziano relation at high temperature. This renders a significant drop of eta prime mass at high temperature signaling a restoration of the U(1)A, and the Goldstone character of etaprime.
