Measurements of Top Quark Spin Observables in tt̅ Events Using Dilepton Final States in √s = 8 TeV PP Collisions with the ATLAS Detector
(Springer Verlag, 2018-09-12)
Measurements of top quark spin observables in tt¯ events are presented based on 20.2 fb−1 of s=8 TeV proton-proton collisions recorded with the ATLAS detector at the LHC. The analysis is performed in the dilepton final ...
Combination of Inclusive and Differential tt̅ Charge Asymmetry Measurements Using ATLAS and CMS Data at √s =7 and 8 TeV
This paper presents combinations of inclusive and differential measurements of the charge asymmetry (AC) in top quark pair (tt̅) events with a lepton + jets signature by the ATLAS and CMS Collaborations, using data from ...
Search for Flavor-Changing Neutral Currents in Top Quark Decays T → Hc and T → Hu in Multilepton Final States in Proton-Proton Collisions at √s =13 TeV with the ATLAS Detector
Flavor-changing neutral currents are not present in the Standard Model at tree level and are suppressed in loop processes by the unitarity of the Cabibbo-Kobayashi-Maskawa matrix; the corresponding rates for top quark decay ...
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 Resonances in the Mass Distribution of Jet Pairs with One or Two Jets Identified as B -Jets in Proton-Proton Collisions at √s =13 TeV with the ATLAS Detector
A search for new resonances decaying into jets containing b-hadrons in pp collisions with the ATLAS detector at the LHC is presented in the dijet mass range from 0.57 to 7 TeV. The data set corresponds to an integrated ...
Properties of g → bb̅ at Small Opening Angles in pp Collisions with the ATLAS Detector at √s =13 TeV
The fragmentation of high-energy gluons at small opening angles is largely unconstrained by present measurements. Gluon splitting to b-quark pairs is a unique probe into the properties of gluon fragmentation because ...
Search for Higgs Boson Pair Production in the bb̅WW* Decay Mode at √s=13 TeV with the ATLAS Detector
A search for Higgs boson pair production in the bb̅WW* decay mode is performed in the bb̅ℓνqq final state using 36.1 fb⁻¹ of proton-proton collision data at a centre-of-mass energy of 13 TeV recorded with the ATLAS detector ...
Measurements of Inclusive and Differential Fiducial Cross-Sections of tt̅ Production with Additional Heavy-Flavour Jets in Proton-Proton Collisions at √s=13 TeV with the ATLAS Detector
This paper presents measurements of tt¯ production in association with additional b-jets in pp collisions at the LHC at a centre-of-mass energy of 13 TeV. The data were recorded with the ATLAS detector and correspond to ...
Search for Supersymmetry in Final States with Missing Transverse Momentum and Multiple B-Jets in Proton-Proton Collisions at √s=13 TeV with the ATLAS Detector
A search for supersymmetry involving the pair production of gluinos decaying via third-generation squarks into the lightest neutralino (χ{_1^{˜0}}) is reported. It uses LHC proton-proton collision data at a centre-of-mass ...
Search for Heavy Particles Decaying into Top-Quark Pairs Using Lepton-Plus-Jets Events in Proton–Proton Collisions at √s=13 TeV with the ATLAS Detector
A search for new heavy particles that decay into top-quark pairs is performed using data collected from proton–proton collisions at a centre-of-mass energy of 13 TeV by the ATLAS detector at the Large Hadron Collider. The ...
