Here we demonstrate an example of photon-induced events in Herwig.
To start, create a new work directory:
mkdir photon_induced
cd photon_induced
Next, download below input/config/analysis files in your work directory.
1. MadGraph configure script: this is a script for generating a sample of unweighted yy > ll events with MadGraph.
