Unformatted text preview: UNIVERSITY OF CALIFORNIA, SANTA BARBARA Department of Physics Physics 221A Quantum Field Theory Fall 2007 Prof: Joe Polchinski [email protected] http://www.kitp.ucsb.edu/~joep/Web221A/221A.html FINAL EXAM Open notes, homework, solutions, Srednicki (the text, not the person). Please do not discuss the test with anyone but me before the due time. I will check my email regularly, and post any corrections/clarifications on the course web page. Begin: Tuesday, Dec. 11, noon. Due: Wednesday, Dec. 12, noon in my office, KITP 2319 (except for those who have made other arrangements). 1. Consider a theory in d = 4 with three real scalar fields A , B , and C , and the following Lagrangian density: L = 1 2 ( A A + B B + C C + m 2 A A 2 + m 2 B B 2 + m 2 C C 2 ) g 2 AB 2 h 2 CB 2 . There might be other terms in L but you wont need them (in particular you wont need counterterms)....
