Isolating the polarization modes of electroweak bosons provides an important probe for the gauge and Higgs sectors of the Standard Model (SM). Furthermore, it represents a source of discriminating power between the SM and new physics models. The Run 2 dataset and the foreseen luminosities of the next LHC runs will enable polarization measurements in multi-boson processes. Therefore a more complete theoretical understanding is needed for the the polarization-structure description of such processes. After recalling the main issues that arise when separating polarizations at the amplitude level, I will present some recent developments in the Monte Carlo description of polarized bosons (up to NLO accuracy), together with a selection of phenomenological results at the LHC . Special focus will be dedicated to boson-pair production and vector-boson scattering.
