Description
Multiboson production provides a powerful framework to probe the electroweak sector of the Standard Model, allowing direct access to triple and quartic gauge couplings. During Run 2 of the LHC, major experimental milestones were achieved, with the observation and measurement of electroweak diboson and triboson processes, marking the first experimental sensitivity to quartic gauge couplings at the TeV scale.
Vector Boson Scattering (VBS) plays a central role in these studies, offering unique sensitivity to the gauge structure of the Standard Model. In particular, polarized VBS, although experimentally challenging, provides new opportunities to further test the electroweak sector and enhance sensitivity to effects beyond Standard Model expectations.
Looking ahead, the increased dataset from Run 3 and the High-Luminosity LHC will significantly extend the reach of multiboson measurements. Future analyses are expected to improve precision and strengthen constraints on new physics contributions. This contribution reviews past achievements, summarizes the current experimental status, and discusses future prospects for electroweak physics with multiboson production at the LHC.
