5 Summary

Measurements of scattering at DANE will fulfill a number of aims :

(a)

they will test the predictions of PT ,

(b)

they will fix the sub-threshold zero in the channel,

(c)

they will provide an independent check of low energy phases, and

(d)

they will anchor partial wave analyses of data at higher masses, and so allow a better determination of the couplings of the scalars and so crucial for understanding their quark composition [11,36].

For all these, measurements of the angular distributions over as complete a coverage as possible is vital [33,37]. We have much to learn.
To conclude : the importance of measuring scattering at DANE should not be underestimated. Consequently, we eagerly await the precision measurements of the KLOE detector at DANE.
It is a pleasure to thank Rinaldo Baldini, Stefano Bellucci, André Courau, Jürg Gasser, David Morgan and Jorge Portolés for numerous invaluable discussions.
