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 ve ctor operator. There is a simple nonlocal "dipole" field-theory that realiz es this deformation. We present evidence that this theory is realized in th e setting of "pinned-branes". The dipoles correspond to open strings that a rch 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.
