Higgs Physics with the ATLAS detector at the LHC

What gives masses to the particles? We believe that it is related to electroweak symmetry breaking which raises the hierarchy problem, the huge gap between the weak and Planck scales. The LHC experiments is addressing some of these questions and at the same time rising new ones. Recent cosmological-observation raised additional puzzles: What is the source of dark matter and energy? We explore experimental and theoretical methods to improve our knowledge regarding these issues. We also propose to use optical atomic clock spectroscopy to Search for Higgs-mediated interactions in atoms at table top experiments
