MG5_aMC@NLO Plugin

A valid installation of MG5_aMC@NLO (2.8+) is necessary in order to generate matrix elements.

If you already have a valid installation, please add the following environment variable pointing to the right directory: MADGRAPH_PATH. Below are the instructions for MG5_aMC@NLO 3.1.0, for a more recent release please visit the MG5_aMC@NLO site.

tar xfz MG5_aMC_v3.1.0.tar.gz
export MADGRAPH_PATH=${PWD}/MG5_aMC_v3_1_0

Once MG5_aMC@NLO is installed, all that’s left is to link the madflow plugin inside the MG5_aMC@NLO folder.

madflow --autolink

If you prefer to link the plugin manually, it is necessary to link the madgraph_plugin folder inside the PLUGIN directory of MG5_aMC@NLO. For instance, if the environment variable $MADGRAPH_PATH is pointing to the MG5_aMC root:

ln -s ${PWD}/madgraph_plugin ${MADGRAPH_PATH}/PLUGIN/pyout
