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 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 ...
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 ...
Search for Higgs Boson Decays to Beyond-The-Standard-Model Light Bosons in Four-Lepton Events with the ATLAS Detector at √s=13 TeV
A search is conducted for a beyond-the-Standard-Model boson using events where a Higgs boson with mass 125 GeV decays to four leptons (ℓ = e or μ). This decay is presumed to occur via an intermediate state which contains ...
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 Heavy Long-Lived Multicharged Particles in Proton-Proton Collisions at √s =13 TeV using the ATLAS Detector
A search for heavy long-lived multicharged particles is performed using the ATLAS detector at the LHC. Data with an integrated luminosity of 36.1 fb⁻¹ collected in 2015 and 2016 from proton-proton collisions at √s=13 TeV ...
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 ...
