AbstractAbstract
[en] A partial-wave analysis of the reaction pi-p-->pi+pi-pi-p at 18 GeV/c has been performed on a data sample of 250 000 events obtained in the Brookhaven experiment E852. The well-known a1(1260), a2(1320) and pi2(1670) resonant states are observed. The existence of the pi(1800), a1(1700) and a4(2040) states is confirmed. The a3(1874) state is also observed. The exotic 1-+ pi1(1600) state produced in the natural parity exchange process is found to decay in the rho(770)pi- channel. A mass-dependent fit results in a resonance mass of 1593±8-47+29 MeV/c2 and a width of 168±20-12+150 MeV/c2

AbstractAbstract
[en] New measurements of peripheral meson production are presented. The data confirm the existence of exotic mesons at 1.4 and 1.6 GeV/c2. The latter state dominates the eta'pi- decay spectrum. The data on eta pi+pi-pi- decay show large strength in several exotic (Jpc = 1- +) waves as well
