Abstract
The results of patial wave analysis of the omega pi- pi0 system, produced in the reaction pi- Be --> pi+ 2pi- 2pi0 Be at beam momentum of 37 GeV are presented. An indication of the resonant type structure with mass near 1.74 GeV and JpMetha=0-0+ in the omega rho- system was found. The decay branching ratio of a2(1320)- to omega pi- pi0 was measured. A wave with JpMetha=2+1+ shows a broad bump at M near 1.7 GeV. The decays pi2(1670)- --> omega rho- and a4(2040)- --> omega rho- were observed for the first time. The bump in the b1(1235)pi wave with exotic quantum numbers Jpc=1-+ at M near 1.7 GeV was observed.
