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

Electroweak bosons, W± and Z⁰, are massive weakly-interacting particles insensitive to the strong interaction. Therefore, they are unique probes in pp and heavy-ion collisions and provide a medium-blind probe of the initial state of the heavy-ion collision. In the ALICE experiment, the productions of W± and Z⁰ are studied by exploiting their leptonic decay channels in a wide rapidity region. In this contribution, the differential cross sections for W± and Z⁰ in pp collisions at √s= 13 TeV, p--Pb collisions at √sNN= 8.16 TeV and Pb--Pb collisions at √sNN= 5.02 TeV are reported. The charged particle multiplicity dependence of W bosons and the associated hadrons production in pp collisions at √s= 13 TeV is also shown.
