A PWA of $p\omega$ in photoproduction using CLAS
ORAL
Abstract
We will present results of a partial wave analsysis, (PWA), on the reaction $\gamma p\rightarrow p\omega$ with the $\omega$ decaying to $\pi^{+}\pi^{-}\pi^{\circ}$. The decay of the $\omega$ into its three pseudoscalar final state provides information on the polarization of the $\omega$ which in turn provides an additional handle in the PWA analysis. These data are analalyzed using a covariant tensor formalism which provides a natural mechnaism for including both $t$-channel contributuions as well as background terms in the PWA. The results of such an analysis are a decomposition of into the $s$-wave contributions to the final state. The mass dependence of the intensity and phase of these partial waves can be used to deduce information about the baryon resonances that couple to $p\omega$ final states.
