Physics 253b Assignment #2 updated Sunday 14 th February, 2010, 08:39 As usual, I would rather have you talk to me than read a text book. But if you want inspiration, you might want to read sections I-9, III-1, III-2, III-3 and the first few pages of VI-8 of Zee and review parts of chapter II as needed. You may also want to look at chapter 12 of Peskin on the renormalization group — but at this point it might just confuse you. We will come back to it. Do the problems below. Make sure that you follow the rules of coherence. Typeset your solution in L A T E X file, zip your latex file and any nonstandard input files and/or packages necessary to compile it along with the pdf file it generates and submit the zip file to the appropriate drop box on the web page by Friday Feb. 19. Note that you are encouraged to discuss the problems with

Unformatted text preview: your colleagues in the class. But you must write up your solution entirely on your own. Note also that L A T E X is tremendously useful, but can be very frustrating if you are trying to nd a bug at the last minute. Make sure to start your work early enough to get help from me if you need it. 2-1 . Consider a theory of three real scalar elds j for j = 1 to 3 and three Dirac fermions j for j = 1 to 3 . We will write these as vectors in an internal space, and write the Lagrangian as L ( ) = 1 2 ~ ~ + i ~ 6 ~ -m 2 2 ~ ~ + g ~ 5 ~ ~ - 4 ~ ~ 2 (2-1.1) Find the renormalization group equation 1...
