There is currently enormous interest in the investigation of how hadron properties may be altered by immersion in matter. There is strong evidence of a reduction in the mass of the rho meson from relativistic heavy ion collisions as well as a hint from a recent experiment on photoproduction in light

The idea that the explicit breaking of scale invariance by the trace anomaly of QCD can be rephrased as a spontaneous breaking has been recently exploited to capture the lowenergy strong interaction dynamics of dense (and also hot) matter in terms of two dilaton fields, the "soft" (ฯ s ) and the "ha
With the explicit breaking of scale invariance by the trace anomaly of QCD rephrased in terms of spontaneous breaking, low-energy strong interaction dynamics of dense and/or hot matter can be effectively captured by -in addition to the Nambu-Goldstone bosons and the vector mesons -two dilaton fields
