As of October 22, 2025, the Large Hadron Collider (LHC) has delivered 500/fb (inverse femtobarns) of integrated luminosity to its major experiments, ATLAS and CMS. The total delivered luminosity is a measure of the total number of particle collisions generated by the accelerator. Reaching 500/fb goes well beyond the original goal for the LHC to deliver 300/fb by the end of Run 3. The PPC loves it!
