In our last post we summarized the Feynman rules for all of the known particles of the Standard Model. Now it’s time to fess up a little about the shortcomings of the Feynman diagram approach to calculations; in doing so, we’ll learn a little more about what Feynman diagrams actually represent as well as the kinds of physics that we must work with at a machine like the LHC.

When one diagram isn’t enough Recall that mesons are bound states of quarks and anti-quarks which are confined by the strong force. This binding force is very non-perturbative; in other words, the math behind our Feynman diagrams is not the right tool to analyze it. Let’s go into more detail about what this means. Easy, right? This is another physical contribution to the interaction between a quark and an anti-quark. Each Feynman diagram represents a term in a mathematical expression. QCD and the lattice.

What information consumes is rather obvious: it consumes the attention of its recipients. Hence a wealth of information creates a poverty of attention, and a need to allocate that attention efficiently among the overabundance of information sources that might consume it. — Herbert Simon The nation that makes a great distinction between its scholars and its warriors will have its thinking done by cowards and its fighting done by fools. — Thucydides Fantasy, abandoned by reason, produces impossible monsters; united with it, she is the mother of the arts and the origin of marvels. — Goya When a task cannot be partitioned because of sequential constraints, the application of more effort has no effect on the schedule.
