Rising Phase-Shift Model and Evidence for Daughters in the Reactionp¯n→π−π+π−

It is shown that many of the features of the recent data on the reaction $\overline{p}n\to {\pi }^{-}{\pi }^{+}{\pi }^{-}$ may be explained without recourse to a Veneziano model. A direct fit of particle parameters is obtained by parametrizing the amplitude in terms of the resonance poles in the two nonexotic channels. The existence of daughters is found to be crucial to the fit to the data. No evidence is seen of higher spin resonances; and in all cases, the daughter mass is not degenerate with the parent mass.
