W±-boson production in p–Pb collisions at √sNN = 8.16 TeV and Pb–Pb collisions at √sNN = 5.02 TeV

2023

The production of the W± bosons measured in p–Pb collisions at a centre-of-mass energy per nucleon–nucleon collision sNN = 8.16 TeV and Pb–Pb collisions at 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 < ycmsμ < 4) rapidity region, in p–Pb collisions, where the centre-of-mass frame is boosted with respect to the laboratory frame, the measurements are performed in the backward (−4.46 < ycmsμ < −2.96) and forward (2.03 < ycmsμ < 3.53) rapidity regions. The W− and W+ production cross se…
