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 ...
Measurement of Jet Fragmentation in Pb+Pb and pp Collisions at √{snn} =5.02 TeV with the ATLAS Detector
This paper presents a measurement of jet fragmentation functions in 0.49 nb⁻¹ of Pb+Pb collisions and 25 pb⁻¹ of pp collisions at √{sNN}=5.02 TeV collected in 2015 with the ATLAS detector at the LHC. These measurements ...
Measurement of the Soft-Drop Jet Mass in pp Collisions at √s =13 TeV with the ATLAS Detector
Jet substructure observables have significantly extended the search program for physics beyond the standard model at the Large Hadron Collider. The state-of-the-art tools have been motivated by theoretical calculations, ...
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 Heavy Resonances Decaying into a W or Z Boson and a Higgs Boson in Final States with Leptons and B-Jets in 36 fb⁻¹ of √s=13 TeV pp Collisions with the ATLAS Detector
A search is conducted for new resonances decaying into a W or Z boson and a 125 GeV Higgs boson in the νν̅bb̅, ℓ^±νbb̅, and ℓ⁺ℓ⁻bb̅ final states, where ℓ^± = e^± or μ^±, in pp collisions at √s=13 TeV. The data used correspond ...
