Query: On the Couplings of the Rho Meson in AdS/QCD   We argue that in generic AdS/QCD models (confining gauge theories dual to
string theory on a weakly-curved background), the couplings g_{rho HH} of any
rho meson to any hadron H are quasi-universal, lying within a narrow band near
m(rho)^2/f(rho). The argument relies upon the fact that the rho is the
lowest-lying state created by a conserved current, and the detailed form of the
integrals which determine the couplings in AdS/QCD. Quasi-universality holds
even when rho-dominance is violated. The argument fails for all other hadrons,
except the lowest-lying spin-two hadron created by the energy-momentum tensor.
Explicit examples are discussed.
