A study of the {omega}{eta} and {omega}{pi}{sup 0} systems produced in the reaction {pi}{sup {minus}}p{r_arrow}{pi}{sup +}{pi}{sup {minus}}4{gamma}n at 18thinspGeV/c
Results are presented on a study of resonant structure in the {omega}{eta} and {omega}{pi}{sup 0} final states produced in {pi}{sup {minus}}p interactions at 18thinspGeV/c where {omega}{r_arrow}{pi}{sup +}{pi}{sup {minus}}{pi}{sup 0}, {pi}{sup 0}{r_arrow}2{gamma}, and {eta}{r_arrow}2{gamma}. Final states, such as {omega}{eta} and {omega}{pi}{sup 0}, which contain a vector meson, are allowed in the extended flux-tube model for the decay of hybrid mesons. In the {omega}{pi}{sup 0} final state, the data exhibit the well-known b{sub 1}(1235) and the {rho}{sub 3}(1690) resonances. A one-pion exchange mechanism is clearly seen for the {rho}{sub 3}(1690). A detailed partial wave analysis of both {omega}{eta} and {omega}{pi}{sup 0} is currently in progress. {copyright} {ital 1998 American Institute of Physics.}
