Micheal E. Peskin received his doctorate in physics from Cornell University and has held research appointments in theoretical physics at Harvard, Cornell, and CEN Saclay. In 1982, he joined the stafff of the Stanford Linear Accelerator Center, where he is now Professor of Physics. Daniel V. Schroeder received his doctorate in physics from Stanford University in 1990. He held visiting appointments at Pomona College and Grinnell College before joining the faculty of Weber State University, where he is now Associate Professor of Physics.

"This is such a serious competitor to Bjorken and Drell that I fear for our royalties."—Prof. J.D. Bjorken, Stanford Linear Accelerator Center"I have used the text of Peskin and Schroeder in teaching several graduate courses. It provides students with nearly all the tools required of the modern field theorist. It is the only field theory text with a thoroughly modern, Wilsonian treatment of renormalization and the renormalization group. Students are left well equipped to tackle research problems in QCD and the electroweak theory."—Prof. Michael Dine, University of California, Santa Cruz"Peskin and Schroeder have written an introductory field theory textbook with the right choice of material at the right level and all presented from a completely modern point of view. It provides a pedagogical introduction to the tools and concepts of field theory that will be of use to students of condensed matter, cosmology, and particle physics alike."—Prof. Jeffrey Harvey, University of Chicago
