Exempel på antiparticle

• In electron-positron plasmas, the theory of dispersion relations is expected to provide predictions for a variety of interesting phenomena unique to particle- antiparticle plasmas.

• Each meson has a corresponding antiparticle (antimeson) where quarks are replaced by their corresponding antiquarks and vice-versa.

• A photon can also be emitted when a particle and its corresponding antiparticle are annihilated (for example, electronpositron annihilation).

• As the radioisotope undergoes positron emission decay (also known as positive beta decay), it emits a positron, an antiparticle of the electron with opposite charge.

• Since then, the antiparticles of many other subatomic particles have been created in particle accelerator experiments.

• For example, the antiparticle of the electron is the positively charged electron, or positron, which is produced naturally in certain types of radioactive decay.

• It also includes the discovery of composite particles and antiparticles that were of particular historical importance.

• The antiparticles are then led into a recombination trap to create antihydrogen.

• When a particle and antiparticle scatter, virtual particles can be exchanged in two qualitatively different ways.

• The remarkable notion of an antiparticle to each fermion particle e.g. the positron as antiparticle to the electron stems from his equation.

• The latter is seen in many processes in which both a particle and its antiparticle are created simultaneously, as in particle accelerators.

• Although the and its antiparticle are usually produced via the strong force, they decay weakly.

• Instead of being states with no antiparticle, these are states that are already filled with a negative energy particle.

• The antiparticle of the electron is the antielectron, which is nearly always called "positron" for historical reasons.

• There are also four antiparticles with opposite charges, made up of the corresponding antiquarks.
