New constraints of initial states in PbPb collisions with Z boson yields and azimuthal anisotropy at $\sqrt{s_{\text{NN}}} = 5.02$ TeV
The differential yields of Z bosons decaying to a pair of leptons are measured in PbPb collisions collected by the CMS experiment at the LHC. The measurements are performed for collisions at 5.02 TeV, using both the muon and electron decay channels. The yields in various centrality bins are compared...
