The antiproton, p , (pronounced p-bar) is the antiparticle of the proton. Antiprotons are stable, but they are typically short-lived, since any collision...

theory, a particle and its antiparticle (for example, a proton and an antiproton) have the same mass, but opposite electric charge, and other differences...

number of "sea quarks" bound by gluons. Thus, when a proton encounters an antiproton, one of its quarks, usually a constituent valence quark, may annihilate...

The Antiproton Decelerator (AD) is a storage ring at the CERN laboratory near Geneva. It was built from the Antiproton Collector (AC) to be a successor...

The Antiproton Accumulator (AA) was an infrastructure connected to the Proton–Antiproton Collider (SppS) – a modification of the Super Proton Synchrotron...

reconfigured from the previous Antiproton Collector (AC) machine. The Extra Low Energy Antiproton ring (ELENA), which takes antiprotons from AD and decelerates...

The Super Proton–Antiproton Synchrotron (or SppS, also known as the Proton–Antiproton Collider) was a particle accelerator that operated at CERN from 1981...

Facility for Antiproton and Ion Research (FAIR) is an international accelerator facility under construction which will use antiprotons and ions to perform...

Antimatter-catalyzed nuclear pulse propulsion (also antiproton-catalyzed nuclear pulse propulsion) is a variation of nuclear pulse propulsion based upon...

Antiprotonic helium is a three-body atom composed of an antiproton and an electron orbiting around a helium nucleus. It is thus made partly of matter,...
