19. Spontaneously Broken Local Symmetry
19.5 Insert (19.55) into L ˆ H of (19.40) and derive (19.56) for the quadratic
terms.
19.6 Insert (19.65) into L ˆ H of (19.40) and derive the quadratic terms of
(19.69).
19.7 Derive (19.71).
19.8 Write the left-hand side of (19.73) in momentum space (as in (19.4)),
ˆ
and show that the inverse of the factor multiplying A
˜ μ is (19.74) without the
‘i’ (cf problem 19.1).
19.9 Verify (19.87).
