Analysis of the Wtb Vertex from the Measurement of Triple-Differential Angular Decay Rates of Single Top Quarks Produced in the T-Channel at √s=8 TeV with the ATLAS Detector
(Springer, 2018-09-24)
The electroweak production and subsequent decay of single top quarks in the t-channel is determined by the properties of the Wtb vertex, which can be described by the complex parameters of an effective Lagrangian. An ...
A New Method to Distinguish Hadronically Decaying Boosted Z Bosons from W Bosons Using the ATLAS Detector
(Springer LLC, 2016-04-28)
The distribution of particles inside hadronic jets produced in the decay of boosted W and Z bosons can be used to discriminate such jets from the continuum background. Given that a jet has been identified as likely resulting ...
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 ...
Search for Long-Lived Charginos Based on a Disappearing-Track Signature in pp Collisions at √s = 13 TeV with the ATLAS Detector
(Springer, 2018-11-05)
This paper presents a search for direct electroweak gaugino or gluino pair production with a chargino nearly mass-degenerate with a stable neutralino. It is based on an integrated luminosity of 36.1 fb⁻¹ of pp collisions ...
Search for Higgs Boson Pair Production in the bb̅bb̅ Final State from pp Collisions at √s̅ = 8 TeV with the ATLAS Detector
(Springer, 2015-09-09)
A search for Higgs boson pair production pp → hh is performed with 19.5 fb⁻¹ of proton-proton collision data at √s̅ = 8 TeV, which were recorded by the ATLAS detector at the Large Hadron Collider in 2012. The decay products ...
Search for New Phenomena in the Dijet Mass Distribution Using PP Collision Data at √s = 8 TeV with the ATLAS Detector
(Amer Physical Soc, 2015-03-01)
Dijet events produced in LHC proton-proton collisions at a center-of-mass energy √s = 8 TeV are studied with the ATLAS detector using the full 2012 data set, with an integrated luminosity of 20.3 fb⁻¹. Dijet masses up to ...
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 ...
Electron and Photon Energy Calibration with the ATLAS Detector Using 2015-2016 LHC Proton-Proton Collision Data
(Institute of Physics Publishing, 2019-03-18)
This paper presents the electron and photon energy calibration obtained with the ATLAS detector using about 36 fb⁻¹ of LHC proton-proton collision data recorded at √s=13 TeV in 2015 and 2016. The different calibration steps ...
Search for Single Production of a Vector-Like Quark via a Heavy Gluon in the 4b Final State with the ATLAS Detector in pp Collisions at √s̅ = 8 TeV
(Elsevier, 2016-05-03)
A search is performed for the process pp → G* → B_{H}b̅ / B̅_{H}b → Hbb̅ → bb̅bb̅ predicted in composite Higgs scenarios, where G* is a heavy colour octet vector resonance and B_{H} a vector-like quark of charge -1/3. The ...
