Semiclassical strings, dipole deformations of Script N = 1 SYM and decoupling of KK modes
Abstract
In this paper we investigate the recently found γ-deformed Maldacena-Nunez background by studying the behavior of different semiclassical string configurations. This background is conjectured to be dual to dipole deformations of Script N = 1 SYM. We compare our results to those in the pure Maldacena-Nunez background and show that the energies of our string configurations are higher than in the undeformed background. Thinking in the lines of [1] we argue that this is an evidence for better decoupling of the Kaluza-Klein modes from the pure SYM theory excitations. Moreover we are able to find a limit of the background in which the string energy is independent of γ, these strings are interpreted as corresponding to pure gauge theory effects.
