Dimuon enhancement in nucleus-nucleus ultrarelativistic interactions

The study of muon pairs in the mass region $1.5<M_{mumu}<2.5$GeV/c$^2$ in 450 GeV/c p-A, 200 GeV/nucleon S-U and 158 GeV/nucleon Pb-Pb collisions is presented. ~In p-A interactions, the dimuon signal mass spectra are well described by a superposition of Drell-Yan and charmed meson semi-leptoni...
