摘要：

The measurement of the charmonium (J/psi, psi') and bottomonium (gamma, gamma', gamma aEuro(3)) resonances and Z (0) boson in nucleus-nucleus collisions provides crucial information on high density QCD matter. The observation of anomalous suppression of J/psi at the CERN-SPS and RHIC is well established but the clarification of some important questions requires equivalent studies of the gamma family, only possible at LHC energies. The Z (0) boson will be produced for the first time in heavy-ion collisions at the LHC and, since its dominant production channel is through q-q fusion, it is an excellent probe of the nuclear modification of quark distribution functions. This paper reports the capabilities of the CMS detector to study quarkonium and Z (0) production in Pb-Pb collisions at 5.5 TeV, through the dimuon decay channel.
