Unformatted text preview: Physics 651 Problem Set 11 (due 12/05/03) This is the final homework. Instead of a project, this is a rather long exercise. If you are busy during that period, you may hand in the homework later, but before the end of the year. Read Chapter 6 and 7. They contain a wealth of information. 1. Summarize in no more than 70 words and 3 equations the basic point of crossing symmetry. Include figures if it helps. 2. Summarize in no more than 80 words and 3 equations the basic point of the optical theorem in perturbation theory. Include figures if it helps. 3. Provide details to the derivation of Eq.(6.58). 4. Provide details to the derivation of the WardTakahashi identity. 5. Problem 6.2(a) (b) only. 6. Problem 7.1 Use PauliVillars regularization. The following 2 problems are for students who plan to take P652 next semester. 7. Use dimensional regularization in the above problem, problem 7.1. Verify that you obtain the same answer. 8. Problem 7.2 1 ...
