Electroweak production of $Z$jj and $W^{\pm}W^{\pm}$jj states at the LHC

TL;DR

This paper reports measurements of electroweak production of Zjj and W^{ ext{±}}W^{ ext{±}}jj states at the LHC, confirming Standard Model predictions and setting limits on anomalous gauge couplings.

Contribution

First measurements of electroweak Zjj and same-charge WWjj production at 8 TeV, with results consistent with the Standard Model and constraints on anomalous couplings.

Findings

Measured fiducial cross sections agree with Standard Model

Set 95% CL limits on anomalous gauge couplings

Used 20.3 fb^{-1} of ATLAS data at 8 TeV

Abstract

Measurements of fiducial cross sections for the electroweak production of two jets in association with a $Z$ boson and in association with a pair of same-electric-charge $W$ bosons are presented. The measurements are performed using $20.3~$fb$^{-1}$ of proton-proton collision data collected at a center-of-mass energy of $\sqrt{s}=8$~TeV by the ATLAS experiment at the Large Hadron Collider. The measured fiducial cross sections are in agreement with the Standard Model predictions. Limits at 95\% confidence level are set on anomalous triple and quartic gauge couplings.
