In this talk, we present the qualitative reduction of the mass of η′-meson 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 temperature-dependent gluon condensates.
