Query: On the interpretation of Feynman diagrams, or, did the LHC experiments
  observe $H \rightarrow \gamma \gamma$?   According to the received view Feynman diagrams are a bookkeeping device in
complex perturbative calculations. Thus, they do not provide a representation
or model of the underlying physical process. This view is in apparent tension
with scientific practice in high energy physics, which analyses its data in
terms of `channels'. For example the Higgs discovery was based on the
observation of the decay $H \rightarrow \gamma\gamma$ -- a process which can be
easily represented by the corresponding Feynman diagrams. I take issue with
this tension and show that on closer analysis the story of the Higgs discovery
should be told differently.
