However, it doesn't give much insight into why the numbers are what they are. Long ago Hooft argued that QCD could be understood most simply when the “three'” of the three colors was taken to be a large number. But nobody could compute anything like a reduced matrix element with this idea. Recently, people have begun to marry these two stories. I'll tell you a bit about them both, put them together, and see what we find. Remarkable regularities emerge. Coffee, tea and cookies will be available in DUAN G1B31 beginning at 3:45 p.m.
