Collider physics is a branch of particle physics that focuses on the study of subatomic particles by colliding them at extremely high speeds. This research area aims to understand the fundamental forces and particles that make up the universe by observing the results of these collisions. Colliders such as the Large Hadron Collider (LHC) at CERN in Switzerland are used to produce high-energy collisions between particles, which can lead to the discovery of new particles and the testing of theoretical models of particle interactions. Collider physics plays a crucial role in advancing our understanding of the fundamental building blocks of the universe and the nature of the forces that govern them.
