gluon-gluon fusion

Asked by Dontlearnphysics on 2021-05-16

I'm new in particle physics and madgraph. Can anybody tell me how to generate the diagrams of process "g g > z h"? I imported the SM model and input the following code "g g > z h", then there was a warning:

Command "generate g g > z h" interrupted with error:
NoDiagramException : No amplitudes generated from process Process: g g > z h WEIGHTED=4 @1. Please enter a valid process

I will be very grateful if you can help me with this problem

Maybe you should read this paper: 1507.00020 <https://arxiv.org/abs/1507.00020>

If not then you need to use another model than the Standard Model.

Cheers,

Olivier
