Search for pair production of Higgs bosons in the b(b)over-barb(b)over-bar final state using proton-proton collisions at root s=13 TeV with the ATLAS detector
A search for Higgs boson pair production in the bb¯¯bb¯¯ final state is carried out with up to 36.1 fb−1 of LHC proton-proton collision data collected at s√=13 TeV with the ATLAS detector in 2015 and 2016. Three ...
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 , ...
