Vector Deformations of N=4 Super-Yang-Mills Theory, Pinned Branes, and Arched Strings

We study a deformation of N=4 Super-Yang-Mills theory by a dimension-5 vector operator. There is a simple nonlocal dipole field-theory that realizes this deformation. We present evidence that this theory is realized in the setting of pinned-branes. The dipoles correspond to open strings that arch out of the brane. We find the gravitational dual of the theory at large N. We also discuss the generalization to the (2,0) theory.
