Extended Data Fig. 1: Feynman diagrams for the H boson-mediated EW ZZ production contributions.
From: Measurement of the Higgs boson width and evidence of its off-shell contributions to ZZ production
Here, f refers to any ℓ, ν, or q. The tree-level diagrams featuring VBF production are grouped together in the upper row, and those featuring VH production are grouped in the lower row. The interaction displayed in each diagram is meant to progress from left to right. Each straight, curvy, or curly line refers to the different set of particles denoted. Straight, solid lines with no arrows indicate the line could refer to either a particle or an antiparticle, whereas those with forward (backward) arrows refer to a particle (an antiparticle).
