Search for Heavy Majorana Neutrinos with the ATLAS Detector in pp Collisions at √s̅ = 8 TeV
(Springer, 2015-07-29)
A search for heavy Majorana neutrinos in events containing a pair of high-p{T} leptons of the same charge and high-p{T} jets is presented. The search uses 20.3 fb⁻¹ of pp collision data collected with the ATLAS detector ...
Measurement of the Production of a W Boson in Association with a Charm Quark in pp Collisions at √s=7 TeV with the ATLAS Detector
(Springer, 2014-05-16)
The production of a W boson in association with a single charm quark is studied using 4.6 fb⁻¹ of pp collision data at√s = 7 TeV collected with the ATLAS detector at the Large Hadron Collider. In events in which a W boson ...
Search for the Standard Model Higgs Boson Decay to μ⁺μ⁻ with the ATLAS Detector
(Elsevier Science B. V., 2014-11-10)
A search is reported for Higgs boson decay to μ⁺μ⁻ using data with an integrated luminosity of 24.8 fb⁻¹ collected with the ATLAS detector in pp collisions at √s̅ = 7 and 8 TeV at the CERN Large Hadron Collider. The observed ...
Performance of the ATLAS Muon Trigger in pp Collisions at √s̅ = 8 TeV
(EDP Sciences, 2015-03-13)
The performance of the ATLAS muon trigger system is evaluated with proton-proton collision data collected in 2012 at the Large Hadron Collider at a centre-of-mass energy of 8 TeV. It is primarily evaluated using events ...
Search for a Heavy Neutral Particle Decaying to εμ, ετ, or μτ in pp Collisions at √s = 8 TeV with the ATLAS Detector
(American Physical Society, 2015-07-14)
This Letter presents a search for a heavy neutral particle decaying into an opposite-sign different-flavor dilepton pair, e^{±}μ^{∓}, e^{±}τ^{∓}, or μ^{±}τ^{∓} using 20.3 fb⁻¹ of pp collision data at √s̅ = 8 TeV collected ...
Measurement of the tt̅ Production Cross-Section as a Function of Jet Multiplicity and Jet Transverse Momentum in 7 TeV Proton-Proton Collisions with the ATLAS Detector
(Springer, 2015-01-08)
The tt̅ production cross-section dependence on jet multiplicity and jet transverse momentum is reported for proton-proton collisions at a centre-of-mass energy of 7 TeV in the single-lepton channel. The data were collected ...
Search for Invisible Particles Produced in Association with Single-Top-Quarks in Proton-Proton Collisions at √s = 8 TeV with the ATLAS Detector
(EDP Sciences, 2015-02-18)
A search for the production of single-top-quarks in association with missing energy is performed in proton–proton collisions at a centre-of-mass energy of √s = 8 Tev with the ATLAS experiment at the large hadron collider ...
Measurement of the Parity-Violating Asymmetry Parameter α_b and the Helicity Amplitudes for the Decay Λ_b^0 → J/ψΛ⁰ with the ATLAS Detector
(American Physical Society, 2014-05-27)
A measurement of the parity-violating decay asymmetry parameter, α_b, and the helicity amplitudes for the decay Λ_b^0 → J/ψ(μ⁺μ⁻)Λ⁰(pπ⁻) is reported. The analysis is based on 1400 Λ_b^0 and Λ̅_b^0 baryons selected in 4.6 ...
Measurements of Charge and CP Asymmetries in B-Hadron Decays Using Top-Quark Events Collected by the ATLAS Detector in PP Collisions at √s̅ = 8 TeV
