I have pretty good handle on non-relativistic quantum mechanics, but I would like to learn about the Standard Model (Quantum Field Theory). What is the best introductory book and/or introductory article on QFT? Thanks Here are some I've heard of: Articles "[URL [Broken] Model: An Introduction Authors: S. F. Novaes (Instituto de Fisica Teorica, UNESP)[/URL] Books B. de Wit and J. Smith. Field Theory in Particle Physics. North Holland, 1986. I. Aitchison and A. Hey. Gauge Theories in Particle Physics. Adam Hilger, 1989. L. Ryder. Quantum Field Theory. Cambridge Univ. Press, 1985. C. Itzykson and B. Zuber. Quantum Field Theory. McGraw Hill, New York, 1980. T. Cheng and L. Li.
