Query: A Conjecture about Hadrons   We conjecture that in the chiral limit of QCD the spectrum of hadrons is
comprised of decoupled, reducible chiral multiplets. A simple rule is developed
which identifies the chiral representations filled out by the ground-state
hadrons. Our arguments are based on the algebraic structure of superconvergence
relations derived by Weinberg from the high-energy behavior of pion-hadron
scattering amplitudes.
