Antiproton | Elementary Particles, Antimatter & CERN | Britannica
2024年11月13日 · antiproton, subatomic particle of the same mass as a proton but having a negative electric charge and oppositely directed magnetic moment. It is the proton’s antiparticle.
Antimatter - CERN
At CERN, physicists make antimatter to study in experiments. The starting point is the Antiproton Decelerator, which slows down antiprotons so that physicists can investigate their properties.
A 16-parts-per-trillion measurement of the antiproton-to ... - Nature
2022年1月5日 · Here we report on a new comparison of the proton/antiproton charge-to-mass ratios with a fractional uncertainty of 16 parts per trillion.
antiproton, viewed in photographic-emulsion stack experiments. –Led by Gerson Goldhaber of Segre’s group. •The right picture is a bubble chamber image. –The antiproton enters from the …
The Antiproton Decelerator - CERN
The Antiproton Decelerator (AD) is a unique machine that produces low-energy antiprotons for studies of antimatter, and “creates” antiatoms. A proton beam coming from the PS ( Proton …
The Antiproton - The Pasayten Institute
Enter the antiproton. Just like the proton, the antiproton is a tiny bag of subnuclear goo. Virtual pions and gluons and other quantum effects are all dressed up in the antiproton package …
Observation and Annihilation: The Discovery of the Antiproton
2021年2月27日 · I show that the discovery was an extended event and was seen by the physicists involved as emerging from a combination of supporting experiments—the counter-based …
Antiproton Physics - Frontiers
Today, the antiproton source of CERN is mainly devoted to experiments dealing with atomic physics and fundamental symmetries. In spite of several interesting proposals, no low-energy …
Fifty years of antiprotons – CERN Courier
2005年11月2日 · It is 50 years since Emilio Segrè, Owen Chamberlain and their group first created an antiproton. Lynn Yarris describes their achievement at Berkeley’s Bevatron in 1955.
