Single-top Cross Section Measurements at ATLAS
The single-top production cross section is one third that of the top-pair production cross section at the LHC. During the first year of data taking, assuming an average luminosity of 10cms and a CMS energy of 14 TeV, the determination of the major contributions to the total single-top cross section should be achievable. Comparisons between the measured cross sections and the theoretical predict...
متن کاملTop quark production in the ATLAS detector of the LHC
Top quark has been re-discovered at LHC in 2010 by the CMS and the ATLAS experiments. The top quark is the heaviest known elementary particle, and its properties might offer a hint of physics beyond the Standard Model. Therefore, it is interesting to measure them as precisely as possible. We present a summary of a variety of measurements relating to the top quark production in pp collisions wit...
متن کاملStudy of top-quark pair cross-section measurement in the dilepton channel with the ATLAS detector at the LHC
The top quark is the heaviest of the known fundamental particles in the Standard Model (SM) with a mass of 173.3±1.1GeV. It is the sixth quark in the SM and the weak isospin partner of the bottom quark. Properties such as the mass and the cross section have been measured since its discovery in 1995 with great precision at the proton-antiproton Fermilab Tevatron Collider, Chicago at a centre-of-...
متن کاملSingle-top quark studies in ATLAS
We present the result of searches for single top-quark production in the t and Wt-channels in 7 TeV proton-proton collisions with the ATLAS detector using 0.7 fb −1 integrated luminosity. The t-channel search is based on the selection of events with a single lepton (muon or electron), jets and missing transverse energy. The Wt-channel analysis is based on the selection of events with two lepton...
متن کاملTop Quark Physics at the LHC
Even though its existence was predicted a few decades ago, and its discovery was made more than a decade ago, the top quark still plays a major role in the forefront of the experimental and theoretical challenges of high energy physics. At the LHC, the importance of the top quark can be recognized in a number of perspectives over the lifetime of the accelerator and the general purpose detectors...
