Do the Twist

Everyone’s all a-titter about Witten’s latest, which appeared today. He studies Maximal Helicity-Violating amplitudes ($n-2$ gluons of one chirality and $2$ of the other) in perturbative large-N, $\mathcal{N}=4$ Yang-Mills theory. After transforming from momentum space to twistor space, he find that the amplitudes are supported on certain holomorphic curves in twistor space. And he relates this to a computation in the open topological B-model with target space $CP^{3|4}$.

Arvind has a brief summary over at the Table. Me, I’m still wading my way through the 97 page opus.
