ATLAS measurements of multi-boson production

TL;DR

This paper reports on ATLAS measurements of various multi-boson production processes at the LHC, providing detailed cross sections and limits on anomalous couplings to test the Standard Model predictions.

Contribution

It presents the first comprehensive set of measurements of ZZ, WZ, WW, Zγ, and Wγ production at 7 and 8 TeV, including cross sections and anomalous coupling limits.

Findings

Measured total, fiducial, and differential cross sections for multiple boson processes.

Set limits on anomalous triple-gauge couplings with improved precision.

Confirmed consistency with Standard Model predictions within experimental uncertainties.

Abstract

Measurements of electroweak gauge-boson pair-production in sqrt(s) = 7 and 8 TeV pp collisions at the LHC probe self-couplings and interference effects to an accuracy of O(10%) or better. ATLAS measurements of ZZ and WZ production at both center of mass energies, and of WW, Zgamma and Wgamma production at sqrt(s) = 7 TeV, are presented. Total, fiducial, and differential cross sections are given, along with limits on anomalous triple-gauge couplings.
