Electroweak boson production in heavy-ion collisions with ALICE

Electroweak boson production in hadronic processes is a clean tool for the investigation of the parton distribution functions (PDFs). This is especially true in heavy-ion collisions at the LHC, where the initial state is largely unconstrained from measurements and important for the interpretation of the system evolution. The ALICE experiment can measure W-perpendicular to and Z(0) bosons at large rapidity, thus accessing a kinematic region where the nuclear PDFs are less constrained. This contribution presents an overview of the recent electroweak measurements with ALICE that provides a clear evidence of nuclear modification of the PDFs.
