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 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 (hep-th/0505100) 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. 1

We examine the leading Regge string states relevant for semi-classical spinning string solutions. Using elementary RNS techniques, quadratic terms in an effective Lagrangian are constructed which describe massive NSNS strings in a space-time with five-form flux. We then examine the specific case of AdS5 ×S 5, finding the dependence of AdS “energy ” (E0) on spin in AdS (S), spin on the sphere (J), and orbital angular Many of the most remarkable developments in M-theory may be traced to the study of various dualities. Although there is as yet no complete understanding of M-theory in its entirety, it is nevertheless clear that many aspects of the theory are very well captured through dualities of various sorts. In particular, the notion of AdS/CFT duality only achieves

We perform the dimensional reduction of the spacetime of a stack of N D3-branes by the “twist ” identification of a circle to obtain a new Kaluza-Klein Melvin background. In the near-horizon limit the background has the magnetic-flux deformed AdS5 and S5 subspacetime. After analyzing the classical closed string solutions with several angular momenta in different directions of the deformed spacetimes we obtain two string solutions. The first solution describes a circular closed string located at a fixed value of deformed AdS5 radius while rotating simultaneously in two planes in deformed AdS5 with equal spins S. The second solution describes a string rotating in deformed S5 with two equal angular momenta J in the two rotation planes. We also apply the mechanism of the “twist ” identification to the 11d M-theory with a stack N M2-branes and then use T duality to find the spacetime of a stack of N D3- branes with magnetic flux. In the near-horizon limit the background becomes the magnetic-flux deformed AdS5 × S5, in which a classical spinning string solution is obtained. We investigate the small fluctuations in these solution and show that the magnetic fluxes have inclination to improve the stability of the string solutions.
