CDF

Scientists of the Collider Detector at Fermilab collaboration have achieved the most precise measurement to date of the mass of the W boson, one of nature’s force-carrying particles. The measured value shows tension with the value expected based on 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.

For over two decades, Spanish institutions have been collaborating with Fermilab. From the Tevatron era to the lab’s current neutrino experiments, Spain has made important contributions.

The CDF and DZero collaborations at Fermilab announced the discovery of the top quark in 1995, the final undiscovered quark of the six predicted by theory. The biannual prize is given for an outstanding contribution to high-energy and particle physics.

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.

Measuring a certain parameter of particles emerging from Tevatron collisions helps us better understand how the unified electromagnetic and weak forces broke into separate distinct entities in the universe’s early moments.

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.

Researchers found four new particles made of the same four building blocks.

Scientists on the CDF and DZero experiments at the U.S. Department of Energy’s Fermi National Accelerator Laboratory have announced that they have found the final predicted way of creating a top quark, completing a picture of this particle nearly 20 years in the making.
