From Popular Mechanics, April 9, 2022: New research shows the W boson is heavier than scientists expected with the discovery going against the Standard Model of particle physics. Recently, a 400-person team announced the results of data they carefully sifted through of more than four million collisions from the Collider Detector at Fermilab.
From AZO Quantum, April 11, 2022: The W boson, one of nature’s force-carrying particles, has been detected by the Collider Detector at Fermilab (CDF) team, which includes 400 scientists from across the world.
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.
Twenty-five years ago, scientists on the CDF and DZero particle physics experiments at Fermilab announced one of history’s biggest breakthroughs in particle physics: the discovery of the long-sought top quark. The collaborations on the two experiments jointly made the announcement on March 2, 1995, to much fanfare. We take a look back on this day in Fermilab history a quarter-century ago.
From Duke Today, July 17, 2019: Teams behind the 1995 discovery are recognized for first observations of tiny but hefty particle at the heart of matter.
