Development of a time-to-digital converter ASIC for the upgrade of the ATLAS Monitored Drift Tube detector / Wang, Jinhong (Michigan U.) ; Liang, Yu (Hefei, CUST ; Michigan U.) ; Xiao, Xiong (Michigan U.) ; An, Qi (Hefei, CUST) ; Chapman, John W. (Michigan U.) ; Dai, Tiesheng (Michigan U.) ; Zhou, Bing (Michigan U.) ; Zhu, Junjie (Michigan U.) ; Zhao, Lei (Hefei, CUST)
The upgrade of the ATLAS muon spectrometer for high-luminosity LHC requires new trigger and readout electronics for the various elements of the detector. We present the design of a time-to-digital converter (TDC) ASIC prototype for the ATLAS Monitored Drift Tube (MDT) detector. [...]

A Programmable Delay Design for the sTGC Detector at the Upgraded New Small Wheel of the ATLAS Muon Spectrometer / Wang, Jinhong (Michigan U.) ; Guan, Liang (Michigan U.) ; Chapman, John W (Michigan U.) ; Zhou, Bing (Michigan U.) ; Zhu, Junjie (Michigan U.)
We present a programmable time alignment scheme used in an ASIC for the ATLAS forward muon trigger development. The scheme utilizes regenerated clocks with programmable phases to compensate for the timing offsets introduced by different detector trace lengths. [...]

Muon reconstruction efficiency and momentum resolution of the ATLAS experiment in proton–proton collisions at $\sqrt{s}=7$ TeV in 2010 / ATLAS Collaboration
This paper presents a study of the performance of the muon reconstruction in the analysis of proton--proton collisions at $\sqrt{s}=7$ TeV at the LHC, recorded by the ATLAS detector in 2010. This performance is described in terms of reconstruction and isolation efficiencies and momentum resolutions for different classes of reconstructed muons. [...]

The differential production cross section of the $\phi$(1020) meson in $\sqrt{s}$ = 7 TeV pp collisions measured with the ATLAS Detector / ATLAS Collaboration
A measurement is presented of the $\phi ➝ K^+K^−$ production cross section at √s = 7 TeV using pp collision data corresponding to an integrated luminosity of 383 μb$^{−1}$ collected with the ATLAS experiment at the LHC. Selection of $\phi$(1020) mesons is based on the identification of charged kaons by their energy loss in the pixel detector. [...]

Measurement of the inclusive isolated prompt photon cross section in pp collisions at √s = 7 TeV with the ATLAS detector using 4.6 fb$^{-1}$ / ATLAS Collaboration
A measurement of the cross section for the production of isolated prompt photons in pp collisions at a center-of-mass energy $\sqrt{s}$ = 7 TeV is presented. The results are based on an integrated luminosity of 4.6 fb$^{-1}$ collected with the ATLAS detector at the LHC. [...]

Search for long-lived stopped R-hadrons decaying out-of-time with pp collisions using the ATLAS detector / ATLAS Collaboration
An updated search is performed for gluino, top squark, or bottom squark R-hadrons that have come to rest within the ATLAS calorimeter, and decay at some later time to hadronic jets and a neutralino, using 5.0 and 22.9 fb$^{-1}$ of pp collisions at 7 and 8 TeV, respectively. Candidate decay events are triggered in selected empty bunch crossings of the LHC in order to remove pp collision backgrounds. [...]

Search for charginos nearly mass-degenerate with the lightest neutralino based on a disappearing-track signature in pp collisions at √s = 8 TeV with the ATLAS detector / ATLAS Collaboration
A search is presented for direct chargino production based on a disappearing-track signature using 20.3 fb−1 of pp collisions at √s = 8 TeV collected with the ATLAS experiment at the LHC. In anomaly-mediated supersymmetry breaking (AMSB) models, the lightest chargino is nearly mass-degenerate with the lightest neutralino and its lifetime is long enough to be detected in the tracking detectors by identifying decays that result in tracks with no associated hits in the outer region of the tracking system. [...]

Search for dark matter in events with a hadronically decaying W or Z boson and missing transverse momentum in pp collisions at $\sqrt{s}$ = 8 TeV with the ATLAS detector / ATLAS Collaboration
A search is presented for dark matter pair production in association with a W or Z boson in pp collisions representing 20.3 fb$^{-1}$ of integrated luminosity at $\sqrt{s}$=8 TeV using data recorded with the ATLAS detector at the Large Hadron Collider. Events with a hadronic jet with the jet-mass consistent with a W or Z boson, and with large missing transverse momentum are analyzed. [...]

Search for new phenomena in photon+jet events collected in proton--proton collisions at $\sqrt{s}$ = 8 TeV with the ATLAS detector / ATLAS Collaboration
This Letter describes a model-independent search for the production of new resonances in photon + jet events using 20 inverse fb of proton--proton LHC data recorded with the ATLAS detector at a centre-of-mass energy of $\sqrt{s}$ = 8 TeV. The photon + jet mass distribution is compared to a background model fit from data; no significant deviation from the background-only hypothesis is found. [...]

Search for Microscopic Black Holes in a Like-sign Dimuon Final State using large Track Multiplicity with the ATLAS detector / ATLAS Collaboration
A search for microscopic black holes in a like-sign dimuon final state in proton−proton collisions at √s = 8 TeV is presented. The data were collected with the ATLAS detector at the Large Hadron Collider in 2012 and correspond to an integrated luminosity of 20.3 fb$^{-1}$. [...]
