HighLuminosity

HighLuminosity is a project aiming to significantly increase the luminosity of the Large Hadron Collider (LHC) at CERN. Luminosity refers to the rate of particle collisions within the accelerator. Higher luminosity means more collisions, which in turn increases the probability of rare physics events occurring and being detected. This is crucial for experiments like ATLAS and CMS, which are searching for new particles and phenomena beyond the Standard Model, such as additional Higgs bosons or supersymmetric particles.

The HighLuminosity LHC (HL-LHC) upgrade is a multi-year, multi-billion-dollar endeavor. It involves a series of technological advancements, including the installation of new superconducting magnets, upgraded particle beams, and enhanced detectors. The primary goal is to achieve an integrated luminosity of 3000 to 4000 inverse femtobarns (fb⁻¹) over the operational lifetime of the HL-LHC, a factor of ten increase compared to the LHC's original design. This will allow for more precise measurements of known particles, like the Higgs boson, and open up new frontiers in particle physics discovery. The project is expected to extend the LHC's scientific program into the 2030s and beyond.
