Abstract:
In 2010, the LHC finally saw it’s first proton-proton collisions at a center of mass energy of 7 TeV – the highest energy that has ever been achieved. Since then, the ATLAS experiment has recorded a large dataset and published ~100 papers ranging from rediscovery of the known Standard Model to unprecedented sensitivity in searches for new physics. The end of 2011 concluded with potential tantalizing hints of a Higgs boson.
I will discuss some of those results, focusing on searches for new physics, such as dark matter search in the context of Supersymmetry or search for heavy neutrino as a possible explanation for non-zero masses for the SM neutrinos, without, of course, omitting the Higgs searches.
