In-medium reduction of the η' mass √sNN = 200 GeV Au+Au collisions
A reduction of the mass of the η' (958) meson may indicate the restoration of the UA(1) symmetry in a hot and dense hadronic matter, corresponding to the return of the 9th, "prodigal" Goldstone boson. We report on an analysis of a combined PHENIX and STAR data set on the intercept par...
