Abstract: (APS)
A new partial-wave analysis is applied to the 3π decay of the A2− in the reaction π−p→pπ+π−π− at 5 and 7.5 GeVc. The relative importance of the spins and parities 0−, 1+, 1−, 2+, and 2− are obtained as a function of 3π mass. Only the 2+ spin and parity shows resonant structure. Results are also given on the polarization and momentum-transfer dependence of the A2 and on the mass dependence of the interference of 1+ background with 2+ resonance.References(5)
