The data access components of the CDF experiment Data Handling systems, together with the Data File Catalog, provide both the physicists running an analysis job and the production system running reconstruction jobs with a logical view of their input and output data, and transparent interaction with the storage management components. Overview The next(More)
A measurement of the Higgs boson mass is presented based on the combined data samples of the ATLAS and CMS experiments at the CERN LHC in the H→γγ and H→ZZ→4ℓ decay channels. The results are obtained from a simultaneous fit to the reconstructed invariant mass peaks in the two channels and for the two experiments. The measured masses from the individual(More)
The luminosity calibration for the ATLAS detector at the LHC during pp collisions at √ s = 7 TeV in 2010 and 2011 is presented. Evaluation of the luminosity scale is performed using several luminosity-sensitive detectors, and comparisons are made of the long-term stability and accuracy of this calibration applied to the pp collisions at √ s = 7 TeV. A(More)
The measurement of the jet energy resolution is presented using data recorded with the ATLAS detector in proton-proton collisions at √ s = 7 TeV. The sample corresponds to an integrated luminosity of 35 pb −1. Jets are reconstructed from energy deposits measured by the calorime-ters and calibrated using different jet calibration schemes. The jet energy(More)
Results of a search for new phenomena in events with an energetic photon and large missing transverse momentum in proton-proton collisions at sqrt[s] = 7 TeV are reported. Data collected by the ATLAS experiment at the LHC corresponding to an integrated luminosity of 4.6 fb(-1) are used. Good agreement is observed between the data and the standard model(More)
The direct CP violation parameter Re(ε ′ /ε) has been measured from the decay rates of neutral kaons into two pions using the NA48 detector at the CERN SPS. With 3.3 million KL → π 0 π 0 events collected during the 1998 and 1999 running periods, a result of Re(ε ′ /ε) = (15.0 ± 2.7)×10 −4 has been obtained. The result combined with the published 1997 sample(More)
A search for new heavy particles manifested as resonances in two-jet final states is presented. The data were produced in 7 TeV proton-proton collisions by the LHC and correspond to an integrated luminosity of 315  nb⁻¹ collected by the ATLAS detector. No resonances were observed. Upper limits were set on the product of cross section and signal acceptance(More)
The Atlas collaboration at CERN[1] has adopted the Gaudi software architecture which belongs to the blackboard family: data objects produced by knowledge sources (e.g. reconstruction modules) are posted to a common in-memory data base from where other modules can access them and produce new data objects. The StoreGate has been designed, based on the Atlas(More)
