From http://www.physics.upenn.edu/~chb/index.html: contact? chb at sas dot upenn dot edu When I was taking the first semester of field theory, I began LaTeXing up Sidney Coleman's lecture notes, from the course Physics 253a at Harvard. These notes were written by Brian Hill around 20 years before I took the course from L. Motl in the fall of 2006 (based on these notes, and Peskin and Schroeder). I got around 11 lectures done (out of 28) before the difficulty of doing Feynman diagrams easily made it impossible to continue. There things stood from about 2008 to late 2010. Then, TING Yuan Sen typeset lectures 12 through 28 - all of them! We have completed a first round of editing this work on March 14, 2011 and I have uploaded a somewhat polished version of all the lectures combined in one file. Brian Hill has also contributed a preface to this document. See Notes from Sidney Coleman's Physics 253a. The source files (up to date other than lecture 01-0923) are also contained in this ZIP file. Note that I also fixed some swapped pages in the 1-214 scanned notes. You'll need the feyn font, and the wick.sty file among other packages, if you want to compile our LaTeX files. Lecture 12 requires axodraw4j.sty. For more details of this sort, see this file.
Rest in peace, Prof. Coleman.
