Physicists Achieve Fiendishly Difficult W Boson Mass Measurement, Validating Standard Model

Sep 18, 2024, 05:53 AM

Physicists have made a significant advancement in particle physics by precisely measuring the mass of the W boson, a fundamental particle. This fiendishly difficult measurement aligns with the predictions of the Standard Model, a theory that describes the fundamental forces and particles in the universe. The measurement was achieved through the analysis of proton-proton collision data from the second run of the Large Hadron Collider (LHC) by the CMS Experiment collaboration. This result, reported yesterday, provides further validation for the Standard Model, which has been the cornerstone of particle physics for decades.
