Highlights From ATLAS

For the past three years, experiments at the Large Hadron Collider (LHC) have started exploring physics at the high-energy frontier. Thanks to the superb turn-on of the LHC already a rich harvest of initial physics results has been obtained by the general-purpose experiment ATLAS, as well as its sister-experiment CMS. The initial data has allowed a test, at the highest collision energies ever reached in a laboratory, of the Standard Model (SM) of elementary particles, and to make many searches Beyond the Standard Model (BSM). Important results have already been obtained in the search for the Higgs Boson, which would establish the postulated electro-weak symmetry breaking mechanism in the SM, as well as for BSM physics like Supersymmetry (SUSY), heavy new particles, quark compositeness, and others. The important, and successful, SM physics measurements are giving confidence that the experiment is in good shape for their journey into the uncharted territory of new physics anticipated at the LHC.
