High-Statistics Study ofω0Production

Abstract

We report results from a study of ${\pi }^{-}p\to {\omega }^{0}n$ at 6.0 GeV/c based on 28 000 events from a charged and neutral spectrometer. Background under the ${\omega }^0$ is only 7%, a large improvement over deuterium-bubble-chamber work. Density matrix elements, projected cross sections, and effective trajectories for natural and unnatural exchanges are presented.
