Abstract
A measurement of \(W\) boson production in lead-lead collisions at \(\sqrt{s_{\mathrm {NN}}}=2.76\mathrm {\ TeV}\) is presented. It is based on the analysis of data collected with the ATLAS detector at the LHC in 2011 corresponding to an integrated luminosity of 0.14 \(\mathrm {nb}^{-1}\) and 0.15 \(\mathrm {nb}^{-1}\) in the muon and electron decay channels, respectively. The differential production yields and lepton charge asymmetry are each measured as a function of the average number of participating nucleons \(\langle N_{\mathrm {part}} \rangle \) and absolute pseudorapidity of the charged lepton. The results are compared to predictions based on next-to-leading-order QCD calculations. These measurements are, in principle, sensitive to possible nuclear modifications to the parton distribution functions and also provide information on scaling of \(W\) boson production in multi-nucleon systems.
