The History of Antiprotons

Antiprotons, the one-half of the particle used in the collision at the departed Tevatron at Fermilab, have had a long and distinguished history in the development of elementary particle physics. This CERN Courier article traces its history and all the important milestones in our knowledge due to the discovery of this particle.

Over the decades, antiprotons have become a standard tool for studies in particle physics; the word "antimatter" has entered into mainstream language; and antihydrogen is fast becoming a laboratory for investigations in fundamental physics. At CERN, the Antiproton Decelerator (AD) is now an important facility for studies in fundamental physics at low energies, which complement the investigations at the LHC’s high-energy frontier. This article looks back at some of the highlights in the studies of the antiworld at CERN, and takes a glimpse at what lies in store at the AD.
