M Theory Lesson 5
The gallant kneemo and I have been thinking about (and writing about) this very interesting work of Brown. As Louise has discovered, equation 7.31 on page 96 is indeed very reminiscent of the Veneziano amplitude. It might also be worth noting that the other integrals of this type for n points are precisely the n point functions. Who would have guessed? So much physics just falling out of a bunch of associahedra.
Of course this is what we expect for gluons. Modular operads and other such goodies can be used to deal with higher loops, and higher operads are brought in to investigate other Standard Model particles. It's still early days for M-theory, but that vacuum seems to have disappeared in a puff of smoke. Perhaps a few more people will become interested in it soon, because one begins to suspect that the String picture, built with manifolds upon manifolds, is not actually relevant to real physics at all. Oh, dear.
