Bookmark or Share- Antiproton - WikipediaThe antiproton, p. , (pronounced p-bar) is the antiparticle of the proton. Antiprotons are stable, but they are typically short-lived, since any collision with a proton will cause both particles to be annihilated in a burst of energy. The existence of the antiproton with electric charge of −1 e, opposite to the electric charge of +1 e of the ...
- The Antiproton — The Pasayten InstituteEnter 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 around three valance antiquarks. That’s two anti-up quarks and one anti-down quark.
- Measurement of interaction between antiprotons | NatureThe interaction between antiprotons, produced by colliding high-energy gold ions, is shown to be attractive, and two important parameters of this interaction are measured, namely the scattering ...
- Physics - Antiproton Mirrors ProtonAn antiproton experiment has shown to record precision that matter and antimatter particles have equal mass—confirming a basic tenet of the standard model of particle physics. As a test of fundamental physics, the antiproton is weighed against the hydrogen ion—a proxy for the proton.
- Frontiers | Antiproton PhysicsToday, 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 extension of the antiproton program was built at Fermilab.
