The KITP at Santa Barbara is holding a conference on QCD and String Theory this week, and the talks have started to appear online.
Of the ones I’ve taken a quick look at so far, there doesn’t seem to be any obvious recent progress on the 30-year old main question that everyone would like the answer to: can one find a reliable analytical technique for dealing with QCD in the infrared regiion where the effective coupling is strong? The best hope for this in recent years has been the AdS/CFT correspondence, but after seven years the state of the art there still seems to be a long ways from solving the problem one wants to solve (although it does give solutions to other problems). I’m looking forward to seeing what some of the later talks will have to say, including Larry Yaffe’s one tomorrow on “Large N gauge theories: old and new”.
