How to Parametrize an S-Wave Resonance and How to Identify Two-Hadron Composites

Abstract

The question of how one can distinguish quark model states from 2-hadron states near an S-wave theshold is discussed, and the usefulness of the running mass is emphasized as the meeting ground for experiment and theory and for defining resonance parameters.
