Description
A measurement of $Z$ boson production is performed via leptonic decay channels using data samples from the 2015 LHC run obtained at the center-of-mass energy of $\sqrt{s_{_{\rm{NN}}}} = 5.02$ TeV with a total integrated luminosity of 0.49 nb$^{-1}$ and 25.3 pb$^{-1}$ in Pb+Pb and $pp$, respectively. Integrated and differential cross sections are measured for both electron and muon channels in a fiducial detector acceptance defined by a lepton selection of $p_{\rm{T}}^{\ell}>20$ GeV and $|\eta^{\ell}|<2.47(2.5)$ for electrons (muons) with correction for FSR effects. The combined result for both decay channels is compared to NNLO pQCD predictions with different PDF sets calculated with DYNNLO. The large statistical sample of Pb+Pb collisions also allows a high-precision test of the Glauber model.
