Partial Wave Analysis Results for $\gamma p \rightarrow p \omega$ using Data from CLAS at Jefferson Lab

Relativistic quark models predict strong couplings to $p\omega$ --- relative to $N\pi$ --- for some of the {\em missing} $N^*$ states. Previous searches for these states in $\gamma p \rightarrow p \omega$ have relied solely on differential cross section measurements. I will present final differential cross section and $\omega$ spin density matrix element measurements obtained from the CLAS $g11a$ dataset. Measurements at $\sim 20$ points in each of 112 $\sqrt{s}$ bins over the range 1.72 GeV $< \sqrt{s} <$ 2.84 GeV have been made ($\sim2000$ total points). These are the first {\em high precision} polarization measurements made for $\omega$ photoproduction. I will also present partial wave analysis results for this channel. These results are the first to be constrained by precise polarization information. Strong evidence for resonance contributions to $\gamma p \rightarrow p \omega$ has been found.
