The mass of the top quark is measured in a data set corresponding to 4.6 $$\text{ fb }^{-1}$$ fb - 1 of proton–proton collisions with centre-of-mass energy $$\sqrt{s}=7$$ s = 7 TeV collected by the ATLAS detector at the LHC. Events consistent with hadronic decays of top–antitop quark pairs with at least six jets in the final state are selected. The substantial background...
This Letter reports the observation of a high transverse momentum Z→bb¯ signal in proton–proton collisions at s=8 TeV and the measurement of its production cross section. The data analysed were collected in 2012 with the ATLAS detector at the LHC and correspond to an integrated luminosity of 19.5 fb−1. The Z→bb¯ decay is reconstructed from a pair of b-tagged jets, clustered with the anti-kt jet algorithm...
The stand-alone test-bench deployed in the past for the verification of the Tile Calorimeter (TileCal) front-end electronics is reaching the end of its life cycle. A new version of the test-bench has been designed and built with the aim of improving the portability and exploring new technologies for future versions of the TileCal read-out electronics. An FPGA-based motherboard with an embedded hardware...
