Proton-proton collisions at LHC offer a unique handle on the study of the polarization of the Standard Model electroweak (EW) bosons, linked to the whole structure of the EW sector and the presence of the Higgs boson. Multivariate analyses will be carried out to study their effect on the LHC Run-3 data. Also, the future ATLAS detector after its Phase-II upgrade should benefit from a larger acceptance coverage potentially enhancing the precision of such measurements. The doctoral student will contribute to the Run-III data analysis as well as preparing future iterations of the analysis will such an extended ATLAS detector, investigating the possibility to use machine learning techniques to improve the measurements.
