Effects of S-wave thresholds

Description

The opening of a new S-wave threshold is frequently accompanied by an abrupt dip in the magnitude of an amplitude for an already-open channel. One familiar example is the behavior of the I=0 S-wave ππ scattering amplitude at KK threshold. Numerous other examples of this phenomenon in recent data are noted, and a unified description of the underlying dynamics is sought
