Abstract:

genie is interfaced to Pythia 8 to perform hadronization of quark-diquark pairs
and to execute the decay of unstable particles. This report describes how to configure
genie to enable or inhibit the decay of (anti)particles, both in total and selected
channels. Some of the complications that arise due to a mismatch in the decay
channels are described.
