Performance of the LHC, ATLAS and CMS in 2011

Abstract

The path taken by the LHC team to reach 3.6 1033 cm- s- instantaneous luminosity, and to deliver 5.6 fb-1 per experiment is summarized. The main performances of the two experiments are highlighted, in particular the way they managed to cope with the already high level of "pile-up". Selected Standard Model and top physics results are given, and the status of the limits on the Higgs boson search by each experiment is summarized. A brief overview of the search for supersymmetry and exotic phenomena is made at the end. © Owned by the authors 2012.
