From CERN, March 16, 2021: The collaboration of TOTEM researchers at CERN and DØ researchers at Fermilab have discovered the oddereon – an elusive three-gluon state predicted almost 50 years ago.
From CERN, Jan. 26, 2021: This week marks the 50th anniversary of the first proton collisions in CERN’s Intersecting Storage Rings, the first hadron collider ever built. To celebrate, see hadron colliders of the last half-century — including the Tevatron and the Large Hadron Collider — through a historical lens, with an eye toward the quest for high luminosity and new energy frontiers.
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!
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.
