Measurement of electroweak-boson production in pp, p-Pb, and Pb-Pb collisions with ALICE at the LHC

Electroweak bosons, W$^{\pm}$ and Z, are important observables in pp and heavy-ion collisions. In pp collisions, the measurements are useful for testing the perturbative QCD. In heavy-ion collisions, the measurements allow us to study the initial-stage effects, which are mainly due to modification of the parton distribution in the nucleus. In the ALICE experiment, the production of W$^{\pm}$ and Z is studied by exploiting their semileptonic decay channels in the wide rapidity region. In this contribution, the results in pp collisions at $\sqrt{s}=$ 13 TeV, p--Pb collisions at $\sqrt{s_{\textrm{NN}}}=$ 8.16 TeV and Pb--Pb collisions at $\sqrt{s_{\textrm{NN}}}=$ 5.02 TeV are reported.
