Top Physics at the LHC
Résumé
In less than two years from now, the Large Hadron Collider (LHC) will provide first proton-proton collisions at sqrt(s) = 14 TeV. The LHC will be a "Top factory" since about 8 millions of top-antitop events will be produced in one year at low luminosity. After the Top quark discovery and first measurements at Tevatron, the LHC will open a new opportunity for precision measurements of the Top quark properties. Prior to data taking, ATLAS and CMS detectors have to be commissioned and precisely calibrated. Further improvements will be achieved with first collisions. Due to the large amount of produced events and clean signal, early Top signals will play an important role in commissioning the detectors. Moreover some of the early LHC physics results could come from Top physics, leading to a major improvement of Top quark understanding and eventually opening a window for physics beyond the standard model.
