 The analytical expressions for [[latex($R_2$)]] Feynman rules can be found in appendix B of [https://arxiv.org/abs/1912.13001 arXiv:1912.13001].

 In order to handle mixed-order senarios, one has to use the version 3.0.1+ of MadGraph5_aMC@NLO.

+In version 3.0.X, the NLO QCD corrections to di-Higgs+jet at [[latex($\mathcal{O}(\alpha_s^3+\alpha_s^4)$)]] is generated by

+In versions 3.1.0+, the generation syntax has been changed [http://amcatnlo.web.cern.ch/amcatnlo/co.htm here]. It is generated by two processes, i.e.,
+{{{
+> import model HEFT_DH_UFO
+> generate p p > h h j / t t~ QCD=3 QED=2 NP=2 [QCD] QCD^2<=6 QED^2<=4 NP^2<=4
+}}}
+and
+{{{
+> import model HEFT_DH_UFO
+> generate p p > h h j / t t~ QCD^2==8 QED^2<=4 NP^2<=4
+}}}
+The second part is the pure interface term at tree level but contributing to [[latex($\mathcal{O}(\alpha_s^4)$)]].
