Study of antiproton annihilation on neutrons into $\omega\pi^{-} \pi^{0}$

Data are presented on antiproton neutron annihilation at rest into omega pi /sup -/ pi /sup 0/ taken with the Crystal Barrel detector at LEAR (CERN) using a liquid deuterium target. The partial wave analysis shows evidence for at least two omega pi vector resonances above the rho (770) ground-state....

Descripción
Sumario:Data are presented on antiproton neutron annihilation at rest into omega pi /sup -/ pi /sup 0/ taken with the Crystal Barrel detector at LEAR (CERN) using a liquid deuterium target. The partial wave analysis shows evidence for at least two omega pi vector resonances above the rho (770) ground-state. Possible evidence for a third rho ' state with a mass around 1180 MeV is discussed. The results are compared to model dependent predictions concerning the nature of the rho ' states. (35 refs).
