As shown in arXiv:hep-th/0405282, the warped deformed conifold has two
bosonic massless modes, a pseudoscalar and a scalar, that are dual to the phase
and the modulus of the baryonic condensates in the cascading gauge theory. We
reconsider the scalar mode sector, mixing fluctuations of the NS-NS 2-form and
the metric, and include non-zero 4-d momentum kΞΌβ. The resulting pair of
coupled equations produce a discrete spectrum of m42β=βkΞΌ2β which is
interpreted as the spectrum of JPC=0+β glueballs in the gauge theory.
Similarly, we derive the spectrum of certain pseudoscalar glueballs with
JPC=0ββ, which originate from the decoupled fluctuations of the RR
2-form. We argue that each of the massive scalar or pseudoscalar modes we find
belongs to a 4-d massive axial vector or vector supermultiplet. We also discuss
our results in the context of a finite length throat embedded into a type IIB
flux compactification.Comment: LaTeX, 29 pages, 4 eps figure
