In the Standard Model of particle physics, the Higgs field plays a crucial role by spontaneously breaking the underlying electroweak symmetry. This process gives rise to a massive Higgs boson and three massless Goldstone bosons. The massless Goldstone bosons are then absorbed into the W and Z bosons, transforming them into their longitudinal components and giving them mass. It is thus interesting to study longitudinal polarizations of W and Z bosons. In this presentation, I will discuss the latest diboson polarization studies conducted at ATLAS with WZ and ZZ diboson events, and I will focus on new results on diboson polarization fraction measurements at high energies as well as the first observation of radiation amplitude zero effects using WZ events.
