Abstract

Measurements of electroweak-bosons in heavy-ion collisions with ALICE are reported. They are measured at large rapidities, via their (di)muonic decay: Z → μ⁺ μ^- and W^± → μ^± ν. The Z production and nuclear modification factor in Pb--Pb collisions at √s__{\rm NN} = 5.02 TeV are presented and compared to theoretical predictions with or without nuclear modifications of the Parton Distribution Functions. Measurements of electroweak-boson production in p--Pb collisions at √s__{\rm NN} = 5.02 and 8.16 TeV are also presented and discussed.
