(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
The production yield of Z bosons is measured in the electron and muon decay channels in Pb+Pb collisions at √sNN=5.02 TeV with the ATLAS detector. Data from the 2015 LHC run corresponding to an integrated luminosity of ...
