Measurement of t-channel production of single top quarks and antiquarks in pp collisions at 13 TeV using the full ATLAS Run 2 data sample
| Resumo: | This paper presents the measurement of fiducial and differential cross sections for both the inclusive and electroweak production of a same-sign W-boson pair in association with two jets (\( W^{\pm}W^{\pm}jj \)) using 139 fb\(^{-1}\) of proton-proton collision data recorded at a centre-of-mass energy of \( \sqrt{s} = 13 \) TeV by the ATLAS detector at the Large Hadron Collider. The analysis is performed by selecting two same-charge leptons, electron or muon, and at least two jets with large invariant mass and a large rapidity difference. The measured fiducial cross sections for electroweak and inclusive \( W^{\pm}W^{\pm}jj \) production are \( 2.92 \pm 0.22 \text{ (stat.)} \pm 0.19 \text{ (syst.)} \) fb and \( 3.38 \pm 0.22 \text{ (stat.)} \pm 0.19 \text{ (syst.)} \) fb, respectively, in agreement with Standard Model predictions. The measurements are used to constrain anomalous quartic gauge couplings by extracting 95\% confidence level intervals on dimension-8 operators. A search for doubly charged Higgs bosons \( H^{\pm\pm} \) that are produced in vector-boson fusion processes and decay into a same-sign W boson pair is performed. The largest deviation from the Standard Model occurs for an \( H^{\pm\pm} \) mass near 450 GeV, with a global significance of 2.5 standard deviations. |
