Evidence for Single Top-Quark Production in the S-Channel in Proton-Proton Collisions at √s̅ = 8 TeV with the ATLAS Detector Using the Matrix Element Method
(Elsevier Science Bv, 2016-03-08)
This Letter presents evidence for single top-quark production in the s-channel using proton-proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS detector at the CERN Large Hadron Collider. The analysis is ...
Differential Top-Antitop Cross-Section Measurements as a Function of Observables Constructed from Final-State Particles Using pp Collisions at √s̅ = 7 TeV in the ATLAS Detector
Various differential cross-sections are measured in top-quark pair tt̅ events produced in proton-proton collisions at a centre-of-mass energy of √s̅ = 7 TeV at the LHC with the ATLAS detector. These differential cross-sections ...
Search for New Phenomena in Events Containing a Same-Flavour Opposite-Sign Dilepton Pair, Jets, and Large Missing Transverse Momentum in √s̅ =13 TeV pp Collisions with the ATLAS Detector
To probe the W tb vertex structure, top-quark and W-boson polarisation observables are measured from t-channel single-top-quark events produced in proton-proton collisions at a centre-of-mass energy of 8 TeV. The dataset ...
Evidence of Wγγ Production in pp Collisions at √s̅ = 8 TeV and Limits on Anomalous Quartic Gauge Couplings with the ATLAS Detector
(American Physical Society, 2015-07-16)
This Letter reports evidence of triple gauge boson production pp → W(ℓν)γγ + X, which is accessible for the first time with the 8 TeV LHC data set. The fiducial cross section for this process is measured in a data sample ...
