Grape extension to CepGen

A CepGen plugin for the Grape ep → e(γγ→ℓ⁺ℓ^-)p process definition.

Installation and usage

A version of CepGen is required for all stages of the building and running of this extension. Once set, the CEPGEN_PATH environment variable should be set to the installation path (possibly the location of your cepgen directory if directly cloned from the main repository, or the standard environment libraries path if installed from a RPM/DEB package.

The Grape add-on shared library can then be built the usual "CMake way":

mkdir build && cd build
cmake [-GNinja] ..
[ninja|make -j]

This will provide you with a libCepGenGrape.so shared object than can be passed directly to the main CepGen executable, and steered using one of the example cards provided in the cards directory, for instance:

[path/to/bin/]cepgen -a [path/to/]libCepGenGrape.so -i [path/to/cards/]grape_ep_epee_cfg.py
