Query: I-odd sector of the Klebanov-Strassler theory   The Klebanov-Strassler background is invariant under the Z_2 symmetry I,
which acts by exchanging the bi-fundamental fields A and B, accompanied by the
charge conjugation. We study the background perturbations in the I-odd sector
and find an exhaustive list of bosonic states invariant under the global
SU(2)*SU(2) symmetry. In addition to the scalars identified in an earlier
publication arXiv:0712.4404 we find 7 families of massive states of spin 1.
Together with the spin 0 states they form 3 families of massive vector
multiplets and 2 families of massive gravitino multiplets, containing a vector,
a pseudovector and fermions of spin 3/2 and 1/2. In the conformal
Klebanov-Witten case these I-odd particles belong to the N=1 superconformal
Vector Multiplet I and Gravitino Multiplets II and IV. The operators dual to
the I-odd singlet sector include those without bi-fundamental fields making an
interesting connection with the pure N=1 SYM theory. We calculate the mass
spectrum of the corresponding glueballs numerically and discuss possible
applications of our results.
