‘Huh, that’s funny’: physicists delighted by new measurement for the W boson
From Gizmodo, April 7, 2022: A collaboration of 400 researchers have precisely measured the mass of the W boson and to their surprise found that the boson is more massive than predicted by the Standard Model of particle physics. All the data was collected from experiments at the four-story-tall, 4,500-ton Collider Detector (CDF-II for short) at Fermilab’s Tevatron accelerator.
