Vector boson scattering at the LHC
САЖЕТАК:
The seminar provides an overview of diboson production measurements at the Large Hadron Collider (LHC), with a focus on results from the ATLAS experiment obtained during Run 2 data-taking and offering a look at future developments. Diboson processes involve the production of two electroweak gauge bosons (WW, WZ, ZZ) and are essential for testing the predictions of the Standard Model, particularly the structure of electroweak interactions and gauge boson couplings. In the talk we will distinguish between inclusive diboson production and vector boson scattering (VBS), the latter being a rarer process where two bosons are produced alongside forward jets and is especially sensitive to new physics effects. Measurements of cross sections, differential distributions, and polarization states are discussed, along with interpretations using Effective Field Theory (EFT) to constrain anomalous triple and quartic gauge couplings. Recent results will be presented on the observation of electroweak diboson production in several channels (such as same-sign WW, WZ, and ZZ with jets) and emerging studies of boson polarization, which probe the electroweak symmetry breaking mechanism.
