Particle Physics remains one of the most popular aspects of modern Physics to study. It seeks to understand the Universe at its most fundamental level by examining the building blocks from which the Universe is ultimately constructed. Specifically, The Fundamentals of Particle Physics considers what symmetries exist in nature and how they are represented. As a result, many of its underlying principles can be applied to other areas of Physics. Understanding Particle Physics is therefore essential for Physics undergraduate students. This book provides a comprehensive overview of Particle Physics, with an emphasis on the underlying principles and mathematical structures. In particular, the role of symmetries in nature is explored, as well as how this leads to an understanding of the particle Universe. The book has three main aims. Firstly, to introduce the key concepts of Particle Physics. Secondly, to provide a solid understanding of the Standard Model of Particle Physics, as well as looking beyond to potential future developments in the field. Thirdly, to present the necessary tool-kit required for further exploration in Particle Physics, with each chapter accompanied by exercises to support understanding.
