Title: Gauge theory duals of deformed integrable strings

Abstract: Integrable examples of the AdS/CFT correspondence admit numerous deformations on the AdS side, preserving this integrability. These can be viewed as AdS analogues of the real-beta Lunin-Maldacena deformation of (AdS5 x) S5. I will discuss how we can similarly deform the CFT side, in the setting of noncommutative field theory, to (hopefully) give duals of these deformed strings. The resulting noncommutative gauge theories admit a planar equivalence theorem for their Feynman diagrams, and have twisted superconformal symmetry, providing the first hints of their likely planar integrability.
