It's hard to see in the photos, but the diagram is of the Drell-Yan process, where a quark and antiquark fuse into a photon or other gauge boson, which then decays to a lepton-antilepton pair.

The largest Feynman diagram in the world?
As far as I know, the Feynman diagram embedded in the atrium floor of our physics building is the largest in the world. I often overhear campus tour guides describe the diagram as a kind of "molecule" :-/

Connecting two of your topics together:
The Feynman diagram of the Drell-Yan process appears on a blackboard in Atlas Shrugged Part I. It is not mentioned, and the hand-waving science discussion that follows is cringeworthy, but the rest of the film is much better than I thought it would be.

Nice! The reviews are pretty negative, though.
