Top quark physics with ATLAS & CMS

The potential of the ATLAS and CMS experiments for studying top quark physics at the LHC is reviewed. The measurements of the t (t) over bar production cross section and spin correlations, the top quark mass, its electric charge, the structure of the Wtb vertex and the measurement of the W boson helicities, the sensitivity to anomalous couplings, top quark rare decays through Flavour Changing Neutral Currents and the single top quark production are discussed. The results shown use the full Monte Carlo simulation of ATLAS and CMS and assume a center of mass energy of 14 TeV at the LHC. Integrated luminosities in the range between O(10 pb(-1)) and O(10 pb(-1)) are considered, depending on the physics observables under study.
