Particle Physics, Fourth Edition, provides a short introduction to the study of the fundamental constituents of matter and the forces between them. In order to make this stimulating subject readily accessible to undergraduate students, it emphasises the foundations of the so-called standard model in the interpreation of experimental data, with a minimum of mathematical detail, and is suitable for any student who has previously taken introductory courses in nonrelativistic quantum mechanics and special relativity. The structure of the book is simple. The first three chapters give a brief overview of the subject and introduce some basic ideas that are used extensuvely throughout the rest of the book. This is followed by an outline of the experimental methods used to explore the subject and a series of chapters that discuss the most important componentsof the standard model in more detail. Finally, there is a brief account of some of the significant open questions 'beyond the standard model' that are currently being investigated in laboratories around the world.
