In the standard model, Z0 decays into three gluons via the VVVV box diagram and AVV triangle diagram in lowest-order perturbation theory. We calculated the latter contribution and found it comparable to the former. We also found that the dominant contribution of the Z0ggg via the AVV diagram comes from the longitudinal component of Z0. This fact can be used to reduce the background from Z0ggg.
