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 ...
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 ...
Measurement of the Top Quark Mass in the tt̅ → Lepton + Jets Channel from √s=8 TeV ATLAS Data and Combination with Previous Results
The top quark mass is measured using a template method in the tt̅ → lepton + jets channel (lepton is e or μ) using ATLAS data recorded in 2012 at the LHC. The data were taken at a proton–proton centre-of-mass energy of ...
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 Long-Lived Particles Produced in pp Collisions at √s=13 TeV that Decay into Displaced Hadronic Jets in the ATLAS Muon Spectrometer
A search for the decay of neutral, weakly interacting, long-lived particles using data collected by the ATLAS detector at the LHC is presented. The analysis in this paper uses 36.1 fb⁻¹ of proton-proton collision data at ...
