Unformatted text preview: and m are the bare coupling constant and the bare mass correspondingly. a. (20 pts) Similar to how we did it in class for 4 theory (see also HW 4 from last quarter), rewrite the Lagrangian (1) in terms of renormalized physical Felds , coupling , mass m and the counterterms. By calculating the oneloop propagator and vertex corrections Fnd the divergent ( 1 / with = 6d ) parts of the coecients of the counterterms and Z . (Ignore the tadpole graph.) Note that we do not need the Fnite parts of the counterterms to Fnd ( )! b. (10 pts) Using the results of part a Fnd ( ). 1...
