摘要：

The excitation spectrum of the proton is comprised of many broad overlapping resonances. One tool in helping to understand the nucleon resonance spectrum is omega meson photoproduction off the proton. The CLAS FROST running period using circularly polarized photons on a longitudinally polarized butanol target allowed for the extracton of the helicity asymmetry in omega meson photoproduction off the proton. In this presentation I will show preliminary helicity asymmetry results for this reaction.
