Measurement of the Transverse Polarization of Λ and Λ̅ Hyperons Produced in Proton-Proton Collisions at √s = 7 TeV using the ATLAS Detector
(Amer Physical Soc, 2015-02-10)
The transverse polarization of Λ and Λ̅ hyperons produced in proton-proton collisions at a center-of-mass energy of 7 TeV is measured. The analysis uses 760 μb⁻¹ of minimum bias data collected by the ATLAS detector at the ...
Study of Ordered Hadron Chains with the ATLAS Detector
(Amer Physical Soc, 2018-09-27)
The analysis of the momentum difference between charged hadrons in high-energy proton-proton collisions is performed in order to study coherent particle production. The observed correlation pattern agrees with a model of ...
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
(Springer Verlag, 2017-02-14)
Same- and opposite-sign charge asymmetries are measured in lepton+jets tt̅ events in which a b-hadron decays semileptonically to a soft muon, using data corresponding to an integrated luminosity of 20.3 fb⁻¹ from proton-proton ...
Measurement of the Higgs Boson Mass from the H → γγ and H → ZZ* → 4ℓ Channels in pp Collisions at Center-Of-Mass Energies of 7 and 8 TeV with the ATLAS Detector
(American Physical Society, 2014-09-09)
An improved measurement of the mass of the Higgs boson is derived from a combined fit to the reconstructed invariant mass spectra of the decay channels H → γγ and H → ZZ∗ → 4ℓ. The analysis uses the pp collision data sample ...
Search for the Production of Single Vector-Like and Excited Quarks in the Wt Final State in pp Collisions at √s̅ = 8 TeV with the ATLAS Detector
(Springer Verlag, 2016-02-17)
A search for vector-like quarks and excited quarks in events containing a top quark and a W boson in the final state is reported here. The search is based on 20.3 fb⁻¹ of proton-proton collision data taken at the LHC at a ...
Search for B - L R-Parity-Violating Top Squarks in √s=13 TeV pp Collisions with the ATLAS Experiment
A search is presented for the direct pair production of the stop, the supersymmetric partner of the top quark, that decays through an R-parity-violating coupling to a final state with two leptons and two jets, at least one ...
Measurement of the Production Cross-Section of a Single Top Quark in Association with a Z Boson in Proton-Proton Collisions at 13 TeV with the ATLAS Detector
(Elsevier Science B.V., 2018-11-05)
The production of a top quark in association with a Z boson is investigated. The proton-proton collision data collected by the ATLAS experiment at the LHC in 2015 and 2016 at a centre-of-mass energy of √s = 13 TeV are used, ...
Search for New Phenomena in Events with a Photon and Missing Transverse Momentum in PP Collisions at √s = 8 TeV with the ATLAS Detector
(American Physical Society, 2015-01-27)
Results of a search for new phenomena in events with an energetic photon and large missing transverse momentum with the ATLAS experiment at the LHC are reported. Data were collected in proton-proton collisions at a ...
Search for Invisible Higgs Boson Decays in Vector Boson Fusion at √s = 13 TeV with the ATLAS Detector
(Elsevier B.V., 2019-06-10)
We report a search for Higgs bosons that are produced via vector boson fusion and subsequently decay into invisible particles. The experimental signature is an energetic jet pair with invariant mass of O(1)TeV and O(100)GeV ...
Search for S-Channel Single Top-Quark Production in Proton-Proton Collisions at √s = 8 TeV with the ATLAS Detector
(Elsevier, 2014-11-22)
This Letter presents a search at the LHC for s-channel single top-quark production in proton-proton collisions at a centre-of-mass energy of 8 TeV. The analyzed data set was recorded by the ATLAS detector and corresponds ...
