报告摘要：

Electroweak symmetry breaking explains the origin of the masses of elementary particles via their interactions with the Higgs field. Besides the measurements of the Higgs boson properties, the study of the scattering of massive vector bosons (with spin one) at the Large Hadron Collider allows to probe the nature of electroweak symmetry breaking with an unprecedented sensitivity.ATLAS has recently observed the electroweak production of two jets in association with a Z-boson pair using the full Run 2 data collected during year 2015 to 2018, which marks the new milestone in the study of EWSB.A review will be presented, including the discovery of the Higgs boson in Run 1 and the recent observation of vector boson scattering in Run 2 in the ZZ channel.
