Explore the forefront of theoretical physics with ‘Advanced Concepts in Particle and Field Theory’. This comprehensive textbook, ideal for advanced undergraduates and graduate students, bridges the gap between particle physics, quantum field theory, gravity, and general relativity. Delve into the fundamental building blocks of nature and the quest for their unification. Packed with worked examples, detailed derivations, and historical insights, this book offers a unified understanding of matter at its most basic level. Discover key topics including gauge principles, the Higgs mechanism, and supersymmetry, all presented with conceptual clarity. Originally published in 2015 and now available as Open Access on Cambridge Core, this revised edition is an essential resource for aspiring physicists seeking a deep, interconnected view of fundamental physics.
