Antiparticle and particle annihilation

[bassplayer142]

Is there set formulas on how exactly this works. We learned in class very very quickly about how a electron and positron collide and form two photons. There has to be a direct relation between the photons properties and the electron/positron. Thanks

The "formula" is known as "Quantum Electrodynamics". Pick up a copy of Griffiths' particle physics book if you want the skinny

Antiparticle and particle annihilation is a fundamental process in particle physics, where a particle and its corresponding antiparticle collide and are converted into energy in the form of photons. This process follows the principles of conservation of energy and momentum.

There are set formulas, such as the Dirac equation, that describe the behavior of particles and antiparticles and their interactions. However, the exact mechanism of annihilation is still a subject of ongoing research and understanding.

In the case of an electron and positron collision, the resulting photons have exactly half the energy of the original particles and travel in opposite directions to conserve momentum. This relationship between the properties of the particles and resulting photons is a consequence of the laws of physics and can be described mathematically.

Further research and experimentation in particle physics will continue to provide insights into the specifics of antiparticle and particle annihilation. As scientists, it is our duty to continue exploring and understanding these fundamental processes in order to further our knowledge of the universe.
