Webits measurement via triple Higgs production seems beyond the reach of the LHC [26,27] due to the smallness of the corresponding cross section (around 0:1 fb) [20]. In order to constrain the trilinear Higgs self coupling, a complementary strategy based on the precise measurements of single Higgs production and decay processes was recently proposed.

"WebIn many cases, higher order corrections have been calculated for inclusive cross sections, but not for fully differential cross sections due to the increased complexity. While inclusive corrections are in good approximation applicable to signal predictions, only fully differential corrections are guaranteed to provide accurate predictions for suppressed backgrounds.

This process is curious, because gluons and Higgs particles do not directly interact with each other at all (which is why the gluon remains massless even when the Higgs field is non-zero).
