Abstract
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.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating very compact bibliographies which can be beneficial to authors and readers, and in "proceeding" format which is more detailed and complete.
