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...

description 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-leptonic decay contributions, in agreement with previous experiments when considering a linear A dependence. In nucleus-nucleus reactions, taking only into account these two physical ingredients, a dimuon enhancement both with increasing A$cdot$B and centrality is observed.
