In-Medium η′ Mass Reduction

Research output: Contribution to journalArticlepeer-review


In this talk, we present the reduction of the mass of η′-meson at finite temperature which leads to the enhancement of η′ contributions to the dilepton spectra from relativistic heavy ion collisions. QCD low energy theorem, together with the Witten-Veneziano formula, provides the relation of the η′ mass with gluon condensates.
