Feynman diagrams for lepton flavour violating processes

LFVdiagrams

These are some Feynman diagrams which may be usefull when discussing charged lepton flavour violating processes, e.g. τ→μμμ. To allow users to modifiy them or extend them, the code is provided and users are invited to extend it.

For simplicity, the resulting diagrams can be found on the project github page.

License

The diagrams are partially self drawn, following the feynmf/feynmp documentation, partially they are modified versions of diagrams provided within the Feynman Diagram Library. To comply with their license the resulting diagrams are released under the Creative Commons Attribution-ShareAlike 3.0 license.

The source code that is used to generate the diagram files is licensed under the GNU General Public License, version 2.

Usage

The compilation requires make, python and a current version of pdflatex with the feynmp and hepnicenames packages. The diagrams are generated by executing

make

The resulting diagrams can be found in the gh-pages/pdf_files folder as pdf files or white_png_files and png_files as png files with transparent or white background respectively.

Updating the gh-pages

Following the instructions for synchronising Github Pages, these steps will update the website.

rm -r gh-pages
git clone -b gh-pages [email protected]:<username>/LFVdiagrams.git gh-pages
make
cd gh-pages
make
git add pdf_files/*.pdf png_files/*.png white_png_files/*.png LFVdiagrams.zip LFVdiagrams.tar.gz outputs.html
git commit -m "updated output files"
git push origin gh-pages

lfvdiagrams's Issues

automate fmffile from tex file name

Currently, one must manually ensure that a new diagram file is consistent in its filename and the entry in \begin{fmffile}{target}. During a sloppy creation of a new diagram with copy&paste, the later can get forgotten.

ghp-import

with ghp-import, the gh-pages workflow is simplified
