How well do we know the quantum numbers of possible anti p p. -->. M/sub 1/M/sub 2/ states

Information is available to completely analyze the p anti p ..-->.. ..pi pi.. reaction, allowing more global, large-scale, phenomenological analyses which combine the two experimental data sets in an energy independent, amplitude analysis which also includes pion-nucleon data. It would appear from the preliminary analyses of p anti p ..-->.. M/sub 1/M/sub 2/ angular distributions and polarizations the T-region may indeed contain some very interesting activity. (GHT)
