Dipole deformations of [formula omitted] SYM and supergravity backgrounds with [formula omitted] global symmetry

Abstract

We study SL ( 3 , R ) deformations of a type IIB background based on D5 branes that is conjectured to be dual to N = 1 SYM. We argue that this deformation of the geometry correspond to turning on a dipole deformation in the field theory on the D5 branes. We give evidence that this deformation only affects the KK-sector of the dual field theory and helps decoupling the KK dynamics from the pure gauge dynamics. Similar deformations of the geometry that is dual to N = 2 SYM are studied. Finally, we also study a deformation that leaves us with a possible candidate for a dual to N = 0 YM theory.
