متن کاملThe charmonium and beauty physics programme in ATLAS
The first J/ψ → μμ signal in the ATLAS detector, from 7 TeV proton-proton collisions in the LHC, with integrated luminosity of 6.4 nb was extracted and analysed. The reconstructed invariant mass agrees with the PDG value within statistical uncertainties, whilst the peak width is compatible with Monte Carlo expectations. The kinematic properties of the J/ψ candidates are presented. Two examples ...
متن کاملThe ATLAS online High Level Trigger framework: experience reusing offline software components in the ATLAS trigger
Event selection in the ATLAS High Level Trigger is accomplished to a large extent by reusing software components and event selection algorithms developed and tested in an offline environment. Many of these offline software modules are not specifically designed to run in a heavily multi-threaded online data flow environment. The ATLAS High Level Trigger (HLT) framework based on the GAUDI and ATL...
متن کاملExpected Performance of the ATLAS Experiment, Detector, Trigger and Physics
The studies presented in this volume share several common features, includinguse of the same event samples for Standard Model processes, and the same de-tector description and simulation framework for all samples. Common cross-section assumptions were made. These assumptions, and the Monte Carlogenerator programs employed, are listed. Information is also given on the dif-<lb...
