ATLAS Future Plans: Upgrade and the Physics with High Luminosity

ATLAS is planning a series of detector upgrades to cope with increasing instantaneous luminosity and multiple interactions per crossing to ensure that acceptance to new physics and precision measurements are preserved. During the next several years, LHC is expected to collide protons on protons at a center of mass energy up to 14 TeV with luminosities reaching 1 to 2 x 1034 cm^-2 s^-1, accumulating ~100 fb^-1 per year following a Phase 1 Upgrade (2018). The detector upgrades focus on precision tracking and improved trigger capabilities to sustain higher rates. Subsequently, the LHC plans calls for a five-fold increase in instantaneous luminosity, thereby increasing the delivered luminosity to ~3000 fb^-1 by 2030. The increased luminosity will significantly increase the physics reach of ATLAS building on the recent discovery of the Higgs-like boson. The planned detector upgrades and the impact on the ATLAS physics program will be discussed.
