TL;DR: In this paper, an advanced data monitoring procedure was designed to quickly identify issues that would affect detector performance and ensure that only the best quality data are used for physics analysis, and the validation procedure developed during the 2011 and 2012 LHC data-taking periods, in which more than 98% of the proton-proton luminosity recorded by ATLAS at a centre-of-mass energy of 7-8 TeV had calorimeter data quality suitable for physics analyses.

TL;DR: In this paper, the transverse polarization of Λ and Λ¯ hyperons produced in proton-proton collisions at a center-of-mass energy of 7 TeV is measured.

TL;DR: In this paper, a two-layer pixel detector setup (ATLAS-TPX) is presented for thermal and fast neutron detection and radiation field characterization, which consists of two segmented silicon detectors (256 × 256 pixels, pixel pitch 55 μm, thickness 300 μm and 500 μm) facing each other.

TL;DR: In this article, a study of forward-backward multiplicity correlations and a measurement of the dependence on charged multiplicity of the mean transverse momentum of charged hadrons, measured with respect to the thrust axis, was performed on a high statistics sample of Z(0) decays to multihadronic final states collected by the OPAL Collaboration at LEP.
