... plenary talk on “Recent Progress in Formal Theory”, and Witten gave a public lecture Monday night. Nima Arkani-Hamed was supposed to give a “Concluding Inspirational Talk”, but that appears to have been cancelled.

... you start getting a somewhat baroque structure.” Dimopoulos instead promotes his joint work with Nima Arkani-Hamed on the idea of “split-supersymmetry”, where the supersymmetry breaking scale is very high, so can’t explain the hierarchy problem. One possible experimental signature of such models would be a long-lived gluino. They promote the idea that such a thing would be...

... in theories with less supersymmetry, e.g. the N=5 and N=6 theories. Among the other talks, Nima Arkani-Hamed’s is also about this, advertising the idea that N=8 supergravity is the Simplest QFT . Much of this story is about the N=4 SYM amplitudes and new insights into them and their relations to supergravity amplitudes, with some of this research growing out of and motivated...

I'm still battling with Mathematica too much to write much, though we've had some more great lectures. Nima Arkani-Hamed has given us a great crash-course on LHC physics, which may be available from another school online, so I'll try and dig that out if I can. In the meantime we've been having some stunning evenings here and so I took the opportunity to take a couple of rather...
