=============================================================

Ti*k*Z-Feynman is a LaTeX package allowing Feynman diagrams to be easily

generated within LaTeX with minimal user instructions and without the need of

external programs.  It builds upon the Ti*k*Z package and leverages the graph

placement algorithms from Ti*k*Z in order to automate the placement of many

vertices.  Ti*k*Z-Feynman still allows fine-tuned placement of vertices so that

even complex diagrams can still be generated with ease.

Ti*k*Z-Feynman is made available through the

[Comprehensive TeX Archive Network (CTAN)][ctan] and comes with some thorough

[documentation][documentation] containing a tutorial and many examples.  Please

refer to the [project page][projectpage] for additional information.

Ti*k*Z-Feynman is open source and contribution are welcome.  If you have any

suggestions, feature requests, or have found any bugs, feel free to create a new

issue or pull request on Github.

Below are a few example to demonstrate how easy diagram can be, and how

extensible it can be.  Many more are given in the

[documentation][documentation]:



```latex

\feynmandiagram [horizontal=a to b] {

  i1 -- [fermion] a -- [fermion] i2,

  a -- [photon] b,

  f1 -- [fermion] b -- [fermion] f2,

};

```




```latex

\feynmandiagram [large, vertical=e to f] {

  a -- [fermion] b -- [photon, momentum=\(k\)] c -- [fermion] d,

  b -- [fermion, momentum'=\(p_{1}\)] e -- [fermion, momentum'=\(p_{2}\)] c,

  e -- [gluon]  f,

  h -- [fermion] f -- [fermion] i;

};

```




```latex

\begin{tikzpicture}

  \begin{feynman}

    \vertex[right=1cm of a1] (a2);
