  Exploiting the gauge/gravity correspondence we find the spectrum of
hadronic-like bound states of adjoint particles with a large global charge in
several confining theories. In particular, we consider an embedding of
four-dimensional N=1 supersymmetric Yang-Mills into IIA string theory, two
classes of three-dimensional gauge theories and the softly broken version of
one of them. In all cases we describe the low energy excitations of a heavy
hadron with mass proportional to its global charge. These excitations include:
the hadron's nonrelativistic motion, its stringy excitations and excitations
corresponding to the addition of massive constituents. Our analysis provides
ample evidence for the universality of such hadronic states in confining
theories admitting supergravity duals. Besides, we find numerically a new
smooth solution that can be thought of as a non-supersymmetric deformation of
G_2 holonomy manifolds.
