DescriptionString theory on the warped deformed conifold, which in the low-energy limit was described by Klebanov and Strassler, is by now the only known consistent example of the supergravity dual of a four dimensional confining (supersymmetric) gauge theory. In this work bosonic supergravity excitations over the Klebanov-Strassler background are studied. The excitation correspond to the low-energy states of a dual N=1 supersymmetric gauge theory. Discovered states are distributed among seven supermultiplets, for which the gauge theory description is determined. This investigation is in particular motivated by an example of the low-energy spectrum in the pure glue gauge theory in the model that might be relevant for the new physics at the LHC.
