Prof. Thomson is the author of the most up to date and "user friendliest" book Particle Physics book  !<br>His explanation of (and derived equations with ) Chirality vs. Helicity states is worth the price of the book !<br>This is definitely the book to own if you want to learn and get up to speed with Modern Particle Physics.<br>The section of Neutrino oscillations (and their detection via Nuclear Reactor sources) is unique to this text .<br>I'd recommend studying this book before attempting to learn the intricacies of Quantum Field Theory.<br>There are many great QFT books out there.<br>The book by Prof. Schwartz is fabulous clear, thorough, insightful and fun to read.
