Abstract
A partial-wave analysis of the system omega pi(-)pi(0) has been performed f or the reaction pi(-) + A --> pi(+)2 pi(-)2 pi(0) + A* induced by 37-GeV ne gative pions. A resonance structure with a mass of M approximate to 1.74 Ge V and quantum-number values of J(P)M(eta) = 0(-)0(+) has been observed in t he invariant-mass distribution for this system. The branching fraction for a(2)(1320) decay into omega pi(-)pi(0) has been determined. A broad structu re at M approximate to 1.7 GeV has been revealed in the J(P)M(eta) = 2(+)1( +) partial wave, First observations of the decays pi(2)(1670) --> omega rho (-) and a(4)(2040) --> omega rho(-) are reported.
