Spin Density Matrix of the $\omega$ in the Reaction $\bar{p}p\to \omega {\pi }^0$

Crystal Barrel Collaboration, C. Amsler, F. H. Heinsius +8

The spin density matrix of the $\omega$ has been determined for the reaction $\bar{p}p\to \omega {\pi }^0$ with unpolarized in-flight data measured by the Crystal Barrel LEAR exper…
