Abstract

The spectrum of the linearized equations of IIB supergravity above the Klebanov-Strassler background solution is investigated. It is shown that the spectrum of a scalar particle minimally interacting with the background is degenerate with the spectrum of the graviton (traceless spin-2 mode), and this spectrum is studied in detail. The results are generalized to the more general case of the solution that is known in the literature as a baryonic branch.
