Fig. 1: Feynman diagrams for the leading Higgs boson interactions.
From: A portrait of the Higgs boson by the CMS experiment ten years after the discovery
a–f, Higgs boson production in ggH (a) and VBF (b), associated production with a W or Z (V) boson (VH; c), associated production with a top or bottom quark pair (ttH or bbH; d) and associated production with a single top quark (tH; e,f). g–j, Higgs boson decays into heavy vector boson pairs (g), fermion–antifermion pairs (h) and photon pairs or Zγ (i,j). k–o, Higgs boson pair production through ggH (k,l) and through VBF (m,n,o). The different Higgs boson interactions are labelled with the coupling modifiers κ, and highlighted in different colours for Higgs–fermion interactions (red), Higgs–gauge-boson interactions (blue) and multiple Higgs boson interactions (green). The distinction between a particle and its antiparticle is dropped.
