THE FIRST YEAR OF THE LARGE HADRON COLLIDER: A BRIEF REVIEW
Keyword(s):
The first year of LHC data taking provided an integrated luminosity of about 35 pb-1 in proton–proton collisions at [Formula: see text]. The accelerator and the experiments have demonstrated an excellent performance. The experiments have obtained important physics results in many areas, ranging from tests of the Standard Model to searches for new particles. Among other results, the physics highlights have been the measurements of the W-, Z-boson and [Formula: see text] production cross-sections, improved limits on supersymmetric and other hypothetical particles and the observation of jet-quenching, elliptical flow and J/ψ suppression in lead–lead collisions at [Formula: see text].
