hh production cross section in SM
Dear Madgraph team,
We are interested in pp -> hh process. The main contributions to this process comes from gghh effective vertex. We want to check the compatibility of the cross section values of pp->hh process with the values in https:/
We obtained a SM model including ggh and gghh vertex for Madgraph via adding these effective vertex to Feynrules SM file. But we did not obtained true cross section values for pp->hh process.
Which model in Madgraph gives these values? as far as we understand "heft" includes only ggh vertex, not gghh.
