A framework for vertex reconstruction in the ATLAS experiment at LHC

2010

In anticipation of the first LHC data to come, a considerable effort has been devoted to ensure the efficient reconstruction of vertices in the ATLAS detector. This includes the reconstruction of photon conversions, long lived particles, secondary vertices in jets as well as finding and fitting of primary vertices. The implementation of the corresponding algorithms requires a modular design based on the use of abstract interfaces and a common Event Data Model. An enhanced software framework addressing various physics applications of vertex reconstruction has been developed in the ATLAS experiment. Presented in this paper are the general principles of this framework. A particular emphasis is…

Top physics studies at the LHC in the standard model and beyond with the ATLAS detector

2009

The LHC will be a Top quark factory, producing large numbers of Top quarks even at the initial low luminosities. This will enable a rich program of Top quark Physics to be explored, both within the Standard Model and using Top quarks as probes of Physics Beyond the Standard Model. Recent studies from ATLAS will be presented, including prospects for the measurements of the production of Top pairs and single Top production, angular correlations in the Top decay, and the precision measurement of the Top quark mass. The search for Physics beyond the Standard Model will be illustrated with searches for rare Top decays involving Flavour Changing Neutral Currents, and the reconstruction of tt-bar …

Associated production of weak bosons at the LHC with the ATLAS detector

2009

The study of the associated production of weak vector bosons at the LHC allows to search for New Physics through the measurement of possible deviations of the weak boson self-couplings from the expectation within the Standard Model. The sensitivity of the ATLAS experiment to Standard Model diboson (W+ W-, Wplusmn; Z0, Z0 Z0, W± γ, and Z0 γ) production in pp collisions at = 14 TeV, using final states containing electrons, muons and photons, is presented. These studies use Monte Carlo data sets with full detector simulation from the ATLAS Computer System Commissioning, which furthermore include detailed trigger information as well as effects of detector calibration and alignment corrections. …
