What is an antiproton?

Answer 1

An anti-proton is a particle, the opposite of a proton. In theory every particle has an anti-particle and if a particle collides with it's anti-particle they wll both be destroyed and a large amount of energy will be released.

Anti-protons were first made in a laboratory in 1955, and are routinely made in high energy particle accelerators today.

Answer 2

An antiproton is the antiparticle of the proton. It's an antiproton -- antimatter. It's mass will be the same as that of the proton, and it will have a charge with the same field strength as the proton, but of opposite polarity. It also has an opposite magnetic moment, too. Think of an antiproton as a proton with a negative charge.

An antiproton might be found in the nucleus of an antimatter atom. But in our universe, which is dominated by matter (as opposed to antimatter), the antiproton will be looking for a proton to combine with. This mutual annihilation event will see the entire mass of both particles converted into energy. A link can be found below for more information.

Answer 3

• The positron is the antiparticle of the electron
• The antiproton is the antiparticle of the proton
• The antineutron is the antiparticle of the neutron
• The antineutrino is the antiparticle of the neutrino

Answer 4

When protons are accelerated to high kinetic energy, then made to hit a stationary nucleus (iridium is typically used), anti-protons (and other particles) are created by the collision. At FermiLab and CERN, anti-protons are routinely made in this manner.

Answer 5

An antiproton is the antiparticle of a proton, meaning it has the same mass as a proton but carries a negative charge. When an antiproton collides with a proton, they annihilate each other, releasing high-energy particles. Antiprotons are commonly used in particle physics research and in medical treatments.
