Measurement of the top quark mass in the t(t)over-bar -> lepton plus jets channel from root s=8 TeV ATLAS data and combination with previous results
The top quark mass is measured using a template method in the tt¯→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 ...
Search for long-lived particles produced in pp collisions at root s=13 TeV that decay into displaced hadronic jets in the ATLAS muon spectrometer
(American Physical Society, 2019-03-15)
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 ...
Search for four-top-quark production in the single-lepton and opposite-sign dilepton final states in pp collisions at root s=13 TeV with the ATLAS detector
(American Physical Society, 2019-03-26)
A search for four-top-quark production, t ¯ t t ¯ t , is presented. It is based on proton-proton collision data with a center-of-mass energy √ s = 13 TeV collected by the ATLAS detector at the Large ...
Search for the Production of a Long-Lived Neutral Particle Decaying within the ATLAS Hadronic Calorimeter in Association with a Z Boson from pp Collisions at root s=13 TeV
(American Physical Society, 2019-04-15)
This Letter presents a search for the production of a long-lived neutral particle ( Z d ) decaying within the ATLAS hadronic calorimeter, in association with a standard model (SM) Z boson produced via an intermediate ...
Measurements of inclusive and differential fiducial cross-sections of t(t)over-bar gamma production in leptonic final states at root s=13 TeV in ATLAS
Inclusive and differential cross-sections for the production of a top-quark pair in association with a photon are measured with proton-proton collision data corresponding to an integrated luminosity of 36.1 fb −1 , ...
Observation of electroweak W(+/-)Z boson pair production in association with two jets in pp collisions at root s=13 TeV with the ATLAS detector
An observation of electroweak production in association with two jets in proton–proton collisions is presented. The data collected by the ATLAS detector at the Large Hadron Collider in 2015 and 2016 at a centre-of-mass ...
