Abstract
A search for bosons in the decay channel has been performed in PbPb collisions at with the CMS detector at the LHC, in a data sample. The number of opposite-sign muon pairs observed in the invariant mass range is 39, corresponding to a yield per unit of rapidity () and per minimum bias event of , in the range. Rapidity, transverse momentum, and centrality dependencies are also measured. The results agree with next-to-leading order QCD calculations, scaled by the number of incoherent nucleon-nucleon collisions.
