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.
Physicists often find thrifty, ingenious ways to reuse equipment and resources. What do you do about an 800-ton magnet originally used to discover new particles? Send it off on a months-long journey via truck, train and ship halfway across the world to detect oscillating particles called neutrinos, of course. It’s all part of the vast recycling network of the physics community.
From Texas A&M University, June 26, 2018: Toback points to CDF’s impact in its landmark 700th paper published last year in Physical Review D and in how it’s shed new light on the production rate of charm quarks.
