Exploring the potential scientific value of the ATLAS Experiment on the High-Luminosity LHC
The High-Luminosity Upgrade of the Large Hadron Collider is scheduled to start colliding protons by 2026. This major upgrade to CERN’s flagship particle accelerator will increase the number of collisions by 10 times in the ATLAS experiment. ATLAS is currently preparing for a series of complex upgrades to cope with the increase. These include the installation of state-of-the art detectors, the replacement and upgrade of its trigger system and data acquisition system.
ATLAS will have what discovery opportunities with the upgrade of HL-LHC? How accurately will physicists measure the properties of Higgs boson? How deep will they be capable of probing Standard Model processes to find signs of new physics? The ATLAS Collaboration conducted and published dozens of studies in order to answer these questions. These results have provided valuable input into discussions this week held at the Symposium on the European Strategy for Particle Physics in Granada.
Simone Pagan Griso is the co-convener of the ATLAS Upgrade Physics Group. The results of the ATLAS Upgrade Physics Group are not only informative to the ATLAS collaboration but also to the global particle-physics communities, as they reappraise opportunities and challenges ahead.
