Looks like we’ve got all of our ducks in a row out at DZero.
From the CERN Courier, March 9, 2021: The discovery of an odderon, predicted to exist almost 50 years ago, was the result of a collaboration between CERN and Fermilab using data from the Large Hadron Collider as well as Fermilab’s DZero experiment. The results were presented at a CERN physics talk and are reported in a joint publication on the observations that were made in December 2020.
On July 27, DZero submitted two papers to Physical Review D. One was published on Oct. 13, and the other was accepted for publication on Dec. 9. These two papers constitute a tie for the 499th and 500th publications by the DZero collaboration. It is a noteworthy accomplishment, and DZero has joined a select club.
The top quark is the heaviest known elementary particle, as small as an electron but 340,000 times more massive! We don’t know how small those particles are, only that they are smaller than 1/1000th the size of a proton which itself is 1/100,000th the size of the smallest atom, hydrogen. Millionths, billionths, … soon we’re talking small numbers!
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.
