Do I need to disable QED radition when interfacing with Pythia
Dear Madgraph Team,
I generated the W + 2 photon process with MadGraph and would now like to interface this with Pythia8. Looking at the diagrams the process contains photons from quartic and triple gauge couplings in combination with ISR and FSR. Do I need to disable the QED showering in Pythia in order to avoid double counting, or is this done automatically?
Below is my proc card for completeness.
Thanks for your help!
Cheers,
Veit
