To study particle physics, a solid foundation in several areas is essential. Key prerequisites include quantum mechanics (both nonrelativistic and relativistic), special relativity, classical mechanics, and electrodynamics. Recommended textbooks include "Introduction to Elementary Particles" by Griffiths, "Introduction to Elementary Particle Physics" by Bettini, and "Particle Physics" by Martin and Shaw. For practical understanding, knowledge of solid-state physics and electronics may also be beneficial. Utilizing online resources like syllabi and lecture notes can further aid in structuring self-study.
