Abstract

This paper is giving an overview of recent ATLAS results on the production cross sections of gauge boson pairs decaying leptonically using data from pp collisions at √s = 13 TeV for ZZ and at √s = 8 TeV for W ± Z and W ± W ± at the LHC at CERN. The cross sections are found to be in agreement with the expectations from the Standard Model within the estimated uncertainties. The production cross section measurements also allow for studies of anomalous triple and quartic gauge couplings for which 95% confidence level limits are set.

Highlights

  • The measurement of the production of pairs of electroweak gauge bosons plays a central role in tests of the Standard Model (SM) and in searches for new physics at the TeV scale

  • The Triple Gauge Couplings (TGC) vertex is completely fixed by the electroweak gauge structure and a precise measurement of this vertex, through the analysis of diboson production, is essential to test the high energy behavior of electroweak interactions and to probe for possible new physics in the bosonic sector

  • Mea√surements of the produ√ction cross sections of W ±Z, W ±W ± at center of mass energy s = 8 TeV and ZZ at s = 13 TeV in fully leptonic channel have been performed with the ATLAS detector
