=== Textbook treatments ===
* Chapter 16 of Peskin & Schroeder ({{ISBN|0-201-50397-2}} or {{ISBN|0-201-50934-2}}) applies the "BRST symmetry" to reason about anomaly cancellation in the Faddeev–Popov Lagrangian. This is a good start for QFT non-experts, although the connections to geometry are omitted and the treatment of asymptotic Fock space is only a sketch.
* Chapter 12 of M. Göckeler and T. Schücker ({{ISBN|0-521-37821-4}} or {{ISBN|0-521-32960-4}}) discusses the relationship between the BRST formalism and the geometry of gauge bundles. It is substantially similar to Schücker's 1987 paper <ref>Thomas Schücker. [
