Di- and multiboson measurements in ATLAS

TL;DR

This paper reports on measurements of di- and multiboson production cross sections at the LHC, testing the Standard Model's electroweak sector and searching for new physics through various decay modes at 8 and 13 TeV.

Contribution

The study provides comprehensive measurements of multiple boson production processes at different energies, comparing results to theoretical predictions and setting limits on anomalous gauge couplings.

Findings

Measured cross sections for $ZZ$, $WZ$, $WW$, $WW\gamma$, and $WZ\gamma$ productions.

Results agree with Standard Model predictions within uncertainties.

Constraints placed on anomalous gauge boson couplings.

Abstract

Measurements of the di- and multiboson production cross sections at the LHC constitute stringent tests of the electroweak sector of the Standard Model and provide a model-independent means to search for new physics at the TeV scale. The ATLAS collaboration has performed studies of $ZZ$, $WZ$, $WW$, $WW\gamma$ and $WZ\gamma$ productions in various decay modes at $\sqrt{s}$=8 and 13 TeV, including total, fiducial and differential cross-section measurements. These results are compared to state-of-the art theory predictions and are used to provide constraints on new physics, by setting limits on anomalous gauge boson couplings.
