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.
