Search for single b∗-quark production with the ATLAS detector at √s = 7 TeV
(Elsevier Science, 2013-01)
The results of a search for an excited bottom-quark b* in pp collisions at s√=7 TeV, using 4.7/fb of data collected by the ATLAS detector at the LHC are presented. In the model studied, a single b*-quark is produced through ...
Electron efficiency measurements with the ATLAS detector using 2012 LHC proton-proton collision data
(Springer, 2016-12)
This paper describes the algorithms for the reconstruction and identification of electronsin the central region of the ATLAS detector at the Large Hadron Collider (LHC). Thesealgorithms were used for all ATLAS results with ...
Performance of algorithms that reconstruct missing transverse momentum in s√= 8 TeV proton-proton collisions in the ATLAS detector
(Springer, 2016-09)
The reconstruction and calibration algorithms used to calculate missing transverse momentum (E miss T ) with the ATLAS detector exploit energy deposits in the calorimeter and tracks reconstructed in the inner detector as ...
Probing the W tb vertex structure in t-channel single-top-quark production and decay in pp collisions at s√=8 TeV with the ATLAS detector
(Springer, 2017-02)
To probe the Wtb vertex structure, top-quark and W-boson polarisation observables are measured from t-channel single-top-quark events produced in proton–proton collisions at a centreof-mass energy of 8 TeV. The dataset ...
Measurement of differential cross sections of isolated-photon plus heavy-flavour jet production in pp collisions at s√=8 TeV using the ATLAS detector
(Elsevier Science, 2018-01)
This Letter presents the measurement of differential cross sections of isolated prompt photons produced in association with a b-jet or a c-jet. These final states provide sensitivity to the heavy-flavour content of the ...
Search for long-lived neutral particles decaying into lepton jets in proton--proton collisions at s√ = 8 TeV with the ATLAS detector
(Springer, 2014-11)
Several models of physics beyond the Standard Model predict neutral particles that decay into final states consisting of collimated jets of light leptons and hadrons (so-called "lepton jets"). These particles can also be ...
Search for top-quark decays t→Hq with 36 fb−1 of pp collision data at s√=13 TeV with the ATLAS detector
(Springer, 2018-10)
A search for flavour-changing neutral current decays of a top quark into an up-type quark (q = u, c) and the Standard Model Higgs boson, t → Hq, is presented. The search is based on a dataset of pp collisions at s√ = 13 ...
Search for nonpointing and delayed photons in the diphoton and missing transverse momentum final state in 8 TeV pp collisions at the LHC using the ATLAS detector
(American Physical Society, 2014-09)
A search has been performed, using the full 20.3 fb-1 data sample of 8 TeV proton-proton collisions collected in 2012 with the ATLAS detector at the LHC, for photons originating from a displaced vertex due to the decay ...
Measurement of W±W± vector-boson scattering and limits on anomalous quartic gauge couplings with the ATLAS detector
(Springer, 2016-11)
This paper presents the extended results of measurements of W±W± j j production and limits on anomalous quartic gauge couplings using 20.3 fb−1 of proton–proton collision data at √ s = 8 TeV recorded by the ATLAS detector ...
