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 ...
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 ...
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 ...
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 Low-Mass Resonances Decaying into Two Jets and Produced in Association with a Photon Using pp Collisions at √s = 13 TeV with the ATLAS Detector
(Elsevier B.V., 2019-05-30)
A search is performed for localised excesses in dijet mass distributions of low-dijet-mass events produced in association with a high transverse energy photon. The search uses up to 79.8 fb−1 of LHC proton–proton collisions ...
Search for Higgs Boson Decays into Pairs of Light (Pseudo)Scalar Particles in the γγjj Final State in pp Collisions at √s = 13 TeV with the ATLAS Detector
(Elsevier B.V., 2018-11-05)
This Letter presents a search for exotic decays of the Higgs boson to a pair of new (pseudo)scalar particles, H → αα, where the α particle has a mass in the range 20–60 GeV, and where one of the α bosons decays into a pair ...
Search for Lepton-Flavour-Violating Decays of the Higgs and Z Bosons with the ATLAS Detector
(Springer, 2018-05-15)
A search for new phenomena in final states characterized by high jet multiplicity, an isolated lepton (electron or muon) and either zero or at least three b-tagged jets is presented. The search uses 36.1 fb⁻¹ of √s̅ = 13 ...
Search for Dark Matter and Other New Phenomena in Events with an Energetic Jet and Large Missing Transverse Momentum Using the Atlas Detector
(Springer, 2018-09-27)
Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses proton-proton collision data corresponding to an integrated luminosity of 36.1 ...
Determination of the Strong Coupling Constant αₛ from Transverse Energy-Energy Correlations in Multijet Events at √S=8 TeV Using the ATLAS Detector
(Springer, 2018-09-24)
Measurements of transverse energy-energy correlations and their associated asymmetries in multi-jet events using the ATLAS detector at the LHC are presented. The data used correspond to √s = 8 TeV proton-proton collisions ...
Measurement of the Inclusive Cross-Sections of Single Top-Quark and Top-Antiquark T-Channel Production in pp Collisions at √S=13 TeV with the ATLAS Detector
(Springer Verlag, 2017-04-14)
A measurement of the t-channel single-top-quark and single-top-antiquark production cross-sections in the lepton+jets channel is presented, using 3.2 fb⁻¹ of proton-proton collision data at a centre-of-mass energy of 13 ...
