Electron–positron annihilation
text:
Electron–positron annihilation occurs when an electron (e−) and a positron collide. At low energies, the result of the collision is the annihilation of the electron and positron, and the creation of energetic photons:
- e− + e+ → γ + γ At high energies, other particles, such as B mesons or the W and Z bosons, can be created. All processes must satisfy a number of conservation laws, including:
- Conservation of electric charge. The net charge before and after is zero.
- Conservation of line
