Quantum Field Theory 101

My Answer Attempts

These are my efforts to answer questions from Peskin and Schroeder's "An Introduction to Quantum Field Theory".
  1. Be skeptical reading these answers.
  2. Please email me with questions or errors seen (sweetser@alum.mit.edu)
  3. Generated with Texmacs, so it should look good.
P&S use natural units, where h = c = 1, and L = t = energy-1 = mass-1. This is a very good system, used extensively in high energy physics. I have found it useful to include all the factors of h and c. It requires me to think through everything more carefully, a very good thing. You may ignore the units if you wish, but everything c should be there.
