Abstract

The in-medium properties of the vector mesons at normal nuclear-matter density were studied. A significant difference in the e⁺e^- invariant mass spectra around the p/w region between carbon and copper targets was observed, indicating that the spectral shapes of mesons are modified at normal nuclear-matter density.
