Conversion Guide — An Introduction to Quantum Field Theory → LaTeX

Source: M. E. Peskin and D. V. Schroeder, An Introduction to Quantum Field Theory (Addison-Wesley, 1995). This repo is a faithful LaTeX transcription (incremental). Source PDF: ../An Introduction to Quantum Field Theory.pdf.

Directory layout

main.tex                      master document (book class, XeLaTeX; already written)
chapters/chXX.tex             one chapter file per chapter (ch01–ch22)
chapters/frontmatter.tex      preface / notation / editors' preface
chapters/appendix.tex         appendix
extract/                      raw pdftotext output (INPUT, read-only)
extract_figures.py            figure extraction script (figX.Y.png)
images/figX.Y.png             figures cropped from the source PDF (X.Y = original figure number)

Document structure

• main.tex uses \documentclass[11pt,oneside]{book} with three \parts:
  • Part I — Feynman Diagrams and Quantum Electrodynamics: ch01–ch07
  • Part II — Renormalization: ch08–ch13
  • Part III — Non-Abelian Gauge Theories: ch14–ch22
  • then \appendix (chapters/appendix.tex).
• \numberwithin{equation}{chapter} → equations auto-number (2.1), (3.7), … matching the book. Do not hand-number or \tag anything.
• Chapter-end problems use the \problems[...] macro defined in main.tex (\section*{Problems}\addcontentsline{toc}{section}{Problems}).
• Requires the slashed package (for Feynman slash notation) plus the standard amsmath amssymb amsthm mathtools graphicx booktabs bm enumitem microtype hyperref cleveref.

Per-chapter transcription rules

1. Input: read extract/ pdftotext dump for the chapter. Strip running heads, standalone page numbers, and any extraction artifacts.
2. Output: write chapters/chXX.tex. First line: \chapter{<exact source chapter title>}.
3. Equations: the pdftotext output is a mangled linear rendering. Reconstruct each equation into correct LaTeX using your knowledge of quantum field theory (Lagrangians, Dirac/Pauli matrices, Feynman rules, propagators, loops, renormalization, gauge theories). Preserve the order so auto-numbers match. Display equations → \begin{equation}/align; inline → $...$.
4. Figures: wherever the source shows a figure, insert \begin{figure}[htbp] \centering \includegraphics[width=...]{figX.Y.png} \caption{...} \label{fig:X.Y} \end{figure} using the exact filename from images/ (figures keep their original X.Y numbers).
5. Faithfulness: transcribe prose as-is; fix only pdftotext artifacts (stray line breaks, split words, spacing). Preserve all physics content.
6. In-text references: some refs (e.g. eq:4.48) point to equations the book cites but never numbers — leave them as-is (faithful transcription).
7. Do not \tag, \setcounter, invent figures, or leave Unicode math symbols in the text.

Quality bar

• The chapter must compile under the project's main.tex (xelatex).
• Math must be physically correct standard QFT expressions.
• Keep the book's structure, equation order, and figure numbering exactly.
