(7-61): It is less confusing if the dt has t primed, to compare with (7-60), although, strictly speaking it is OK as it is, as we no longer have t as part of the argument in Soper, so we can use t instead of t primed for the integration variable.

8.7.3. Elastic vs Inelastic Scattering: We are assuming no potential energy is involved in interactions, so no kinetic energy is converted into potential energy (or vice versa). This assumption is implied throughout the text.

See Chap 10 corrections which gives a page you can print, then cut and paste corrections into the text. The changes to Wholeness Chart 10-2 may not be so relevant to QFT newcomers, as that chart is only recommended for veterans of the subject.

After (11-21): change “is not symmetric, and there is” to  is symmetric, but for real A^mu, there is effectively -

After (11-22): change the entire sentence to the following: - By doing Prob. 3, you can show that the free e/m Lagrangian in (11-8) is not symmetric, and thus there is no conserved current. -

This is not a correction, but a note of interest.

The first direct, experimental evidence for light-by-light scattering was found at CERN and reported in early 2019. See https://phys.org/news/2019-03-atlas.html

Under Supersymmetry sub-heading, 3rd line, change “Lagrangian” to “action”. In SUSY, there is a little wrinkle here. See Aitchison, (footnote ref 3 on this page 520), pg. 46 (eq (3.34 there) and pg. 60  , 2nd paragraph there).

Footnote 1: Since writing this, I have investigated the issue and now realize that paths backward in time destructively interfere and do not survive in the classical limit. Thus, Dyson’s quote is accurate. To keep things simple and avoid confusion, PI analyses generally look at paths forward in time, but they could equally well include those backward in time.
