dc.descriptionAnalytic properties of hadronic amplitudes are discussed within the framework of QCD as formulated on the basis of the BRST algebra. Local, composite fields are introduced for hadrons. Given confinement, it is shown that hadronic amplitudes have no thresholds or structure singularities (anomalous thresholds) which are directly related to the underlying quark-gluon structure. In contrast, general amplitudes of QCD must have singularities in channels with non-zero color quantum number, which can be related to unphysical states.
