Search for heavy particles decaying into a top-quark pair in the fully hadronic final state in pp collisions at s√= 13 TeV with the ATLAS detector
(American Physical Society, 2019-02)
A search for new particles decaying into a pair of top quarks is performed using proton-proton collision data recorded with the ATLAS detector at the Large Hadron Collider at a center-of-mass energy of s=13 TeV corresponding ...
Measurements of top quark pair relative differential cross-sections with ATLAS in pp collisions at √ s = 7 TeV
(Springer, 2013-01)
Measurements are presented of differential crosss ections for top quark pair production in pp collisions at 7 TeV relative to the total inclusive top quark pair production cross-section. A data sample of 2.05 fb−1 recorded ...
Measurement of the cross-section of high transverse momentum vector bosons reconstructed as single jets and studies of jet substructure in pp collisions at s√ = 7 TeV with the ATLAS detector
(IOP Publishing, 2014-07)
This paper presents a measurement of the cross-section for high transverse momentum W and Z bosons produced in pp collisions and decaying to all-hadronic final states. The data used in the analysis were recorded by the ...
Electron and photon energy calibration with the ATLAS detector using LHC Run 1 data
(Springer, 2014-11)
This paper presents the electron and photon energy calibration achieved with the ATLAS detector using about 25 fb−1 of LHC proton?proton collision data taken at centre-of-mass energies of s√=7 and 8 TeV. The reconstruction ...
A search for lepton-flavor-violating decays of the Z boson into a τ-lepton and a light lepton with the ATLAS detector
(American Physical Society, 2018-04)
Direct searches for lepton flavor violation in decays of the Z boson with the ATLAS detector at the LHC are presented. Decays of the Z boson into an electron or muon and a hadronically decaying τ lepton are considered. The ...
A neural network clustering algorithm for the ATLAS silicon pixel detector
(IOP Publishing, 2014-10)
A novel technique to identify and split clusters created by multiple charged particles in the ATLAS pixel detector using a set of artificial neural networks is presented. Such merged clusters are a common feature of tracks ...
Search for vectorlike quarks in events with one isolated lepton, missing transverse momentum and jets at 8 TeV with the ATLAS detector
(American Physical Society, 2015-03)
A search has been performed for pair production of heavy vectorlike down-type (B) quarks. The analysis explores the lepton-plus-jets final state, characterized by events with one isolated charged lepton (electron or muon), ...
Luminosity determination in pp collisions at s√ = 8 TeV using the ATLAS detector at the LHC
(Springer, 2016-12)
The luminosity determination for the ATLAS detector at the LHC during pp collisions at √s = 8 TeV in 2012 is presented. The evaluation of the luminosity scale is performed usingseveral luminometers, and comparisons between ...
Study of the rare decays of B0s and B0 mesons into muon pairs using data collected during 2015 and 2016 with the ATLAS detector
(Springer, 2018-12)
A study of the decays B0s → μ+μ− and B0 → μ+μ− has been performed using 26.3 fb−1 of 13 TeV LHC proton-proton collision data collected with the ATLAS detector in 2015 and 2016. Since the detector resolution in μ+μ− invariant ...
