| Abstract: | The measurement of the charmonium (J/ψ, ψ′) and bottomonium (γ, γ′, γ″) resonances and Z
0 boson in nucleus-nucleus collisions provides crucial information on high density QCD matter. The observation of anomalous
suppression of J/ψ at the CERN-SPS and RHIC is well established but the clarification of some important questions requires equivalent studies
of the γ 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. |
