Abstract

We examine the polarization properties exhibited by ^ρ0's and ^ω0's in the reactions ^π-+p→^ρ0+^X0 and ^π-+p→^ω0+charged particles at 15 GeV/c. ^ρ0 production is analyzed in the framework of the triple Regge model. The trajectory coupled to the ^π-^ρ0 is α(t)=(-0.12±0.07)+(0.78±0.21)t in good agreement with the π trajectory. The properties of the system recoiling against the ^ρ0 (off-shell ``^π-''p reaction) are very similar to those of the final states of on-shell ^π-p reactions at the same center-of-mass energy.
