Intersecting D3-branes and holography
We study a defect conformal field theory describing D3-branes intersecting over two space-time dimensions. This theory admits an exact Lagrangian description which includes both two- and four-dimensional degrees of freedom, has $(4,4)$ supersymmetry and is invariant under global conformal transformations. Both two- and four-dimensional contributions to the action are conveniently …
