W±-boson production in p–Pb collisions at √sNN = 8.16 TeV and Pb–Pb collisions at √sNN = 5.02 TeV
Original language description
The production of the W bosons measured in p-Pb collisions at a centre-of-mass energy per nucleon-nucleon collision root sNN = 8.16 TeV and Pb-Pb collisions at root sNN = 5.02 TeV with ALICE at the LHC is presented. The W-+/- bosons are measured via their muonic decay channel, with the muon reconstructed in the pseudorapidity region -4 10 GeV/c. While in Pb-Pb collisions the measurements are performed in the forward (2.5 . In Pb-Pb collisions, the same measurements are presented as a function of the collision centrality. Study of the binary scaling of the W-+/--boson cross sections in p-Pb and Pb-Pb collisions is also reported. The results are compared with perturbative QCD calculations, with and without nuclear modifications of the Parton Distribution Functions (PDFs), as well as with available data at the LHC. Significant deviations from the theory expectations are found in the two collision systems, indicating that the measurements can provide additional constraints for the determination of nuclear PDFs and in particular of the light-quark distributions.
