High-luminosity LHC prospects with the upgraded ATLAS detector

Understand

Run 1 at the LHC was very successful with the discovery of a new boson.

• The boson's properties are found to be compatible with those of the Standard Model Higgs boson.
• It is now revealing the mechanism of electroweak symmetry breaking and (possibly) the discovery of physics beyond the Standard Model that are the primary goals of the just restarted LHC.
• The ultimate precision will be reached at the High-Luminosity LHC phase with a proton-proton centre-of-mass energy of 14 TeV.
