Oct 10, 2015 at 18:23	comment	added	Carlo Beenakker		I would think the two forms are equivalent upon an integration by parts in the action, see page 173.
Oct 10, 2015 at 18:20	comment	added	user78817		Yes, I see that it is their Equation 7.88. But on page 190 where the book carries out the computation to show (1a), (1b), and (1c), they use the Lagrangian $\mathcal{L}'' = -{1\over2}\partial_\mu A_\nu \partial^\mu A^\nu - {{\zeta-1}\over2}(\partial_\nu A^\nu)^2$, which confuses me, as this is different from Equation 7.88.
Oct 10, 2015 at 18:18	comment	added	Carlo Beenakker		the Lagrangian in the first line of the posted scan is their Equation 7.2 on page 172 and in Eq. 7.88 on page 189; it has the form you want, doesn't it?
