This is a really good book and a worthy successor to Halzen and Martin, or even the first volume of Bjorken and Drell. The author shows that the key calculations in relativistic particle physics can be obtained from a relativistic generalisation of Fermi's golden rule and a knowledge of the equations of motion for relativistic particles of spin 0, 1/2 and 1. It is not a book on quantum field theory nevertheless the reader who is prepared for some hard work will come away with a working knowledge of the Standard model of particle physics. That should be enough for most people.<br><br>It is interesting that a knowledge of quantum field theory is not needed to understand the key calculations perhaps quantum field theory is not as important as some people think or make out.<br><br>I would recommend the book to anyone who wants to get up to speed on the standard model and who felt a bit cheated by their undergraduate degree in physics which did not really cover the topic in any great detail.
