Particle physics

Definition

Particle physics is the branch of physics that studies the fundamental particles of the universe and their interactions. It seeks to understand the smallest building blocks of matter, such as quarks, leptons, and bosons, as well as the forces that govern their behavior, including electromagnetic, weak, strong, and gravitational forces. This field connects deeply with concepts in geometric measure theory, especially when analyzing the shapes and structures of particle interactions in high-energy environments.
