Page 6, Eq. 2.13, the first {\cal L} should be L. Also in the subsequent equation 2.14, {\cal L} should be L. (Thanks to Matt Headrick)
Page 17, Eq. 3.5, The state on the right hand side of the equation should be |0> not |j>. (Thanks to Russell Guill)
Page 29, Eq. 3.67, The right hand side should be multiplied by -1. (Thanks to Matt Headrick)
Page 32, right before Eq. 3.78, “Lorentz” should be “Lorenz”. (Thanks to Matt Headrick)
Page 58, Eq. 5.34, the -1/2 after the last sign of equality should be a -1/8. (Thanks to Matt Headrick)
First line of page 59, “section 5.5” should read “section 7.4”. (Thanks to Matt Headrick)
Page 63, Eq. 5.51, one of the \mu indices in the four-gradient of \phi should be raised. Also, the should be no term proportional to m^2 a^2. (Thanks to Matt Headrick)
Page 65, Eq. 5.60, “(p+p’)” should be replaced by “(p_1+p_2)”. Also, the figure there should be little arrows pointing right next to the scalar lines, similar to what happens e.g. in eq. (5.52). (Thanks to Matt Headrick)
Page 67, Eq. 5.66, the “+p_4” at the end of the equation should be a “-p_4”. (Thanks to Matt Headrick)
Page 75, Eq. 6.20, There should be no factor of \nu in this equation. (Thanks to Lauren Pearce)
Page 76, Eq. 6.26, The last line should be divided by (2E)^2. (Thanks to Andrzej Czarnecki)
Page 76, Eq. 6.27 and Page 88, Eq. 7.7, The 32 in the denominator should be a 128. (Thanks to Andrzej Czarnecki)
Page 115, right before Eq. 8.56, “Syzmanzik” should read “Symanzik”. (Thanks to Matt Headrick)
