Description

Higgs boson decays to bosons provide very detailed measurements of its properties and interactions, and shine light on the mechanism of electroweak symmetry breaking. This talk presents the latest measurements of the Higgs boson coupling properties performed by the ATLAS experiment in various bosonic decay channels (WW, ZZ and yy) using the full Run 2 pp collision dataset collected at 13 TeV. Results on production mode cross sections, Simplified Template Cross Sections (STXS), and their interpretations are presented. Specific scenarios of physics beyond the Standard Model are tested, as well as generic extensions within the framework of the Standard Model Effective Field Theory.
