First ‘Run 3’ physics result from the Large Hadron Collider’s compact muon solenoid

On July 5, the LHC roared to life for its third run after three years of continual improvements to the machine as well as to the experiments’ detectors and analysis tools, and immediately reached a record energy of 13.6 TeV. Just three weeks later, the compact muon solenoid (CMS) collaboration was ready for its physics data-taking period.
