Hello All! I'm very interested in learning about particle physics and am wondering which book you guys recommend as a starting point. I'm looking for something in between undergrad and grad. So far it seems like the two best choices are Griffiths' Introduction to Elementary Paticles, and Halzen's Quarks and Leptons. The one thing I'm worried about though is that both of these books are 20 years old. Anybody have any insights? Thanks!
