tikz-feyn Documentation

Build Status

tikz-feyn is a LaTeX package for drawing Feynman diagrams using the PGF/TikZ graphics package.

The package provides a simple, intuitive syntax for constructing Feynman diagrams with minimal code, making it ideal for lecture notes, papers, and presentations in particle physics and quantum field theory.

Quick Start

Installation

Download tikz-feyn.sty and place it in your LaTeX project directory, then use:

\usepackage{tikz-feyn}

Basic Example

\begin{tfeyn}
  \tfcol{a1, a2}
  \tfcol{b1, b2}
  \tf[f]{a1,c1,a2}[r]
  \tf[f]{b1,c3,b2}[l]
  \tf[p]{c1, c3}
\end{tfeyn}

This creates a simple fermion-photon scattering diagram.
