Electroweak-boson production from small to large collision systems with ALICE at the LHC

Nuclear Experiment 2023-03-22 v1

Abstract

Recent measurements of the electroweak-boson production performed by the ALICE Collaboration are reported. The W-boson production was measured at midrapidity in pp collisions at s=13\sqrt{s} = 13 TeV, via the electronic decay of the boson. It was also measured in association with a hadron emitted back-to-back with respect to the electron. In heavy-ion collisions, the W- and Z-boson production was measured at forward rapidity in p--Pb collisions at sNN=8.16\sqrt{s_{\mathrm{NN}}} = 8.16 TeV and Pb--Pb collisions at sNN=5.02\sqrt{s_{\mathrm{NN}}} = 5.02 TeV, in their muonic decay channel. Measurements in pp collisions shed light on multiple parton interactions and colour reconnection mechanisms. In heavy-ion collisions the measurements of electroweak bosons allow to probe the initial state of the collision.
