Particle physics

Particle physics

From Wikipedia, the free encyclopedia
Collision of 2 beams of gold atoms recorded by RHIC
Particle physics is a branch of physics that studies the elementary subatomic constituents of matter and radiation, and their interactions. The field is also called high energy physics, because many elementary particles do not occur under ambient conditions on Earth. They can only be created artificially during high energy collisions with other particles in particle accelerators.
Particle physics has evolved out of its parent field of nuclear physics and is typically still taught in close association with it. Scientific research in this area has produced a long list of particles.
