TL;DR
This paper reviews the LHC's performance in 2011, highlighting the achieved luminosity, experiment capabilities, and key physics results including Standard Model, Higgs searches, and beyond Standard Model explorations.
Contribution
It provides a comprehensive summary of the LHC's operational achievements and physics results in 2011, including performance metrics and search limits.
Findings
Achieved 3.6 x 10^33 cm^-2 s^-1 luminosity
Delivered 5.6 fb^-1 of data per experiment
Set limits on Higgs boson and explored supersymmetry
Abstract
The path taken by the LHC team to reach 3.6 10 cm s instantaneous luminosity, and to deliver 5.6 fb 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.
