Operational experience of the ATLAS Pixel Detector
No full textThe ATLAS Pixel Detector is the innermost detector of the ATLAS experiment at the Large Hadron Collider at CERN, providing high-resolution measurements of charged particle tracks in the high radiation environment close to the collision region. This capability is vital for the identification and measurement of proper decay times of long-lived particles such as b-hadrons, and thus vital for the ATLAS physics program. The detector provides hermetic coverage with three cylindrical layers and three layers of forward and backward pixel detectors. It consists of approximately 80 million pixels that are individually read out via chips bump-bonded to 1744 n-in-n silicon substrates. In this talk, results from the successful operation of the Pixel Detector at the LHC will be presented, including monitoring, calibration procedures, timing optimization and detector performance. The detector performance is excellent: 97,5% of the pixels are operational, noise occupancy and hit efficiency exceed the design specification, and a good alignment allows high quality track resolution
Measurements of the production of P-wave charmonium states through radiative decays at the ATLAS experiment
No full textThe production cross sections of the χc1 and χc2 charmonium states are measured in pp collisions at √s = 7 TeV using 4.5 fb−1 of integrated luminosity recorded by the ATLAS detector at the LHC. The χc states are reconstructed via the radiative decay χc → J/ψ(μ+μ−)γ, where the photons are reconstructed using γ → e+ e− conversion in the detector material. Differential production cross sections for prompt and non-prompt χc1,2 are presented, as well as the fraction of inclusive J/ψ produced by feed-down from the χc states. The results are compared with a range of theoretical predictions. The branching fraction of ℬ (B+ → χc1K+) is measured using the same dataset and χc event selection
Heavy flavor onia production at the ATLAS detector at the LHC
No full textHeavy quark physics is an important part of the ATLAS physics programme. Measurements of J/Ψ and Υ(1S) production cross sections as functions of transverse momenta and rapidity were per- formed at √s = 7 TeV using the collision data gathered by the ATLAS detector at the Large Hadron Collider. New bottomonium triplet states χbJ (3P) were observed
ATLAS Insertable B-Layer
No full textFor the sLHC phase I, the ATLAS detector will be upgraded by the installation of one additional Pixel Detector layer. The new layer will be inserted between the B-layer of the existing pixel detector and a new smaller radius beam-pipe. This upgrade requires development of several new technologies to cope with increased radiation doses to which apparatus will be exposed, significant rise of the particle flux density to be detected, and further improvement of the detector physics performance. One of the means to achieve these goals is significant reduction of the pixel size, use of the deep sub-micron technologies for the read-out chip fabrication, novel materials for the stave construction, advanced methods for detector cooling etc. In the present phase of the projects some key components are being developed in several options
Runaway electron beam stability and decay in COMPASS
No full textThis paper presents two scenarios used for generation of a runaway electron (RE) beam in the COMPASS tokamak with a focus on the decay phase and control of the beam. The first scenario consists of massive gas injection of argon into the current ramp-up phase, leading to a disruption accompanied by runaway plateau generation. In the second scenario, injection of a smaller amount of gas is used in order to isolate the RE beam from high-temperature plasma. The performances of current control and radial and vertical position feedback control in the second scenario were experimentally studied and analysed. The role of RE energy in the radial position stability of the RE beam seems to be crucial. A comparison of the decay phase of the RE beam in various amounts of Ar or Ne was studied using absolute extreme ultraviolet (AXUV) tomography and hard x-ray (HXR) intensity measurement. Argon clearly leads to higher HXR fluxes for the same current decay rate than neon, while radiated power based on AXUV measurements is larger for Ne in the same set of discharges

No full textMeasurement of the top quark mass in the t(t)over-bar -> dilepton channel from root s=8TeVATLAS data
No full textThe top quark mass is measured in the t (t) over bar -> dilepton channel (lepton= e, mu) using ATLAS data recorded in the year 2012 at the LHC. The data were taken at a proton-proton centre-of-mass energy of root s = 8 TeV and correspond to an integrated luminosity of about 20.2 fb(-1). Exploiting the template method, and using the distribution of invariant masses of lepton-b-jetpairs, the top quark mass is measured to be m(top) = 172.99 +/- 0.41(stat)+/- 0.74(syst) GeV, with a total uncertainty of 0.84 GeV. Finally, acombination with previous ATLAS m(top) measurements from root s = 7 TeV data in the t (t) over bar -> dilepton and t (t) over bar -> lepton + jets channels results in m(top) = 172.84 +/- 0.34(stat)+/- 0.61(syst) GeV, with a total uncertainty of 0.70 GeV.

Search for single production of a vector-like quark via a heavy gluon in the 4b final state with the ATLAS detector in pp collisions at root s=8 TeV
No full textA search is performed for the process pp -> G* -> B-H(b) over bar/(B) over bar (H)b -> Hb (b) over bar -> b (b) over barb (b) over bar, predicted in composite Higgs scenarios, where G* is a heavy colour octet vector resonance and B-H a vector-like quark of charge -1/3. The data were obtained from pp collisions at a centre-of-mass energy of 8 TeV corresponding to an integrated luminosity of 19.5 fb(-1), recorded by the ATLAS detector at the LHC. The largest background, multijet production, is estimated using a data-driven method. No significant excess of events with respect to Standard Model predictions is observed, and upper limits on the production cross section times branching ratio are set. Comparisons to the predictions from a specific benchmark model are made, resulting in lower mass limits in the two-dimensional mass plane of m(G*) vs. m(BH). (c) 2016 The Author.
