I have the basics of CM, relativity and non relativistic QM but never went much beyond KG and the Dirac equation. So I need a good intro to QFT, particle physics and the SM. Ideally with an emphasis more on the theoretical side than only experimental. I had a good feeling with "An Introduction to the Standard Model of Particle Physics", W. N. Cottingham, D. A. Greenwood. But I'm not sure. What about "Introduction to Elementary Particles" of D. J. Griffiths, or "Introduction To High Energy Physics" of D. H. Perkins? Others? Which would you suggest?
