The first Z boson measurement in the dimuon channel in PbPb collisions at $\sqrt{s}=2.76 TeV$ at CMS

We present the first measurement of $Z$ bosons in the di-muon channel in Pb-Pb collisions at $\sqrt{s_{NN}} = 2.76$ TeV made by the CMS experiment at the LHC, establishing that no modification is observed with respect to next-to-leading order pQCD calculations, scaled by the number of binary...

description We present the first measurement of $Z$ bosons in the di-muon channel in Pb-Pb collisions at $\sqrt{s_{NN}} = 2.76$ TeV made by the CMS experiment at the LHC, establishing that no modification is observed with respect to next-to-leading order pQCD calculations, scaled by the number of binary collisions. Using a $7.2 \mu$b$^{-1}$ data sample, we report on the 39 $Z$ candidates counted in the di-muon 60-120 GeV/c$^{2}$ invariant mass window, and we detail the $Z$ yield as a function of rapidity ($y$), transverse momentum ($p_{T}$) and centrality. The results are compared to and agree with theoretical predictions within statistical and systematic uncertainties.
