Abstract
— The Higgs boson plays an important role in the Standard Model: it provides mass to the elementary particles through the electroweak spontaneous symmetry breaking (EWSB). Discovered in 2012 by the ATLAS and CMS Collaborations, today the Higgs boson is a very powerful tool to test the validity of SM theory at the TeV scale. The Higgs boson can be produced at proton-proton colliders, such as LHC, in different ways and many decay channels are predicted by the Standard Model. At ATLAS Run-2, this particle is widely studied mainly through its decays in vectors boson pairs (H → ZZ∗, H → WW ∗ and H → γγ). In this context, the latest results, obtained using the dataset collected by the ATLAS experiment during 2015 and 2016 at a center-of-mass energy of 13 TeV, are presented. Experimental techniques and estimates of the main backgrounds will be discussed in detail.
期刊介绍：
La Rivista del Nuovo Cimento is an international peer-reviewed journal. It publishes monographs in all fields of physics. These monographies aim at presenting the state of the art of topical subjects of relevant interest for the community. Usually, authors are invited and topics suggested by the Deputy Editors-in-Chief, but also spontaneous submissions are examined.
