The dilatation operator for defect conformal N=4 SYM

High Energy Physics - Theory 2019-09-27 v1

Abstract

We compute the dilatation operator for local "open string" operators situated at the interface of a certain supersymmetric defect version of N=4\mathcal{N}=4 super-Yang-Mills theory. This field theory is dual to a probe D5-brane intersecting a stack of D3-branes where the number of D3-branes can change between the two sides the interface. DeWolfe and Mann obtained the dilation operator in the special case of an equal number of D3-branes. Using a combination explicit field theory calculations and integrability considerations we are able to extend this result to the general case.
