0 a particle that makes up antimatter, containing the same amount of matter but having the opposite electrical charge that a regular particle has -- 反粒子
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.
