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.

From Physics World, April 7, 2022: Particle physicist Lia Merminga has been appointed the first female director of Fermilab and will begin her term on April 18.
From the BBC, April 7, 2022: Scientists of the CDF collaboration have found a tiny difference in the mass of the W Boson compared with what the theory says it should be – just 0.1%. If confirmed by other experiments, the implications could be enormous and could challenge the Standard Model of particle physics.
From FOX News Chicago, March 29, 2022: For the first time in two years, Fermilab welcomed back visitors on March 28. FOX News asks Fermilab’s Alison Markovitz what is new for the public as the lab reopens and what visitors can expect on the grounds and with outdoor activities.
The Mu2e experiment at Fermilab will look for a never-before-seen subatomic phenomenon that, if observed, would transform our understanding of elementary particles: the direct conversion of a muon into an electron. An international collaboration of over 200 scientists is building the Mu2e precision particle detector that will hunt for new physics beyond the Standard Model.
