Title: | Measurements of W+W−+ 1 jet production cross-sections in pp collisions at p s = 13 TeV with the ATLAS detector | Authors: | Fiolhais, M. C. N. Gonçalo, R. Veloso, F. Wolters, H. ATLAS Collaboration |
Keywords: | Hadron-Hadron scattering (experiments) | Issue Date: | Jun-2021 | Publisher: | Springer Nature | Serial title, monograph or event: | Journal of High Energy Physics | Volume: | 2021 | Issue: | 6 | Abstract: | Fiducial and differential cross-section measurements of W+W− production in association with at least one hadronic jet are presented. These measurements are sensitive to the properties of electroweak-boson self-interactions and provide a test of perturbative quantum chromodynamics and the electroweak theory. The analysis is performed using proton-proton collision data collected at p s = 13TeV with the ATLAS experiment, corresponding to an integrated luminosity of 139 fb−1. Events are selected with exactly one oppositely charged electron-muon pair and at least one hadronic jet with a transverse momentum of pT > 30 GeV and a pseudorapidity of | | < 4.5. After subtracting the background contributions and correcting for detector effects, the jet-inclusive W+W−+ 1 jet fiducial cross-section and W+W−+ jets differential cross-sections with respect to several kinematic variables are measured. These measurements include leptonic quantities, such as the lepton transverse momenta and the transverse mass of the W+W− system, as well as jet-related observables such as the leading jet transverse momentum and the jet multiplicity. Limits on anomalous triple-gauge-boson couplings are obtained in a phase space where interference between the Standard Model amplitude and the anomalous amplitude is enhanced. | URI: | https://hdl.handle.net/10316/104997 | DOI: | 10.1007/JHEP06(2021)003 | Rights: | openAccess |
