| High-statistics differential cross sections and spin density matrix elements for the reaction
gamma p -> p omega have been measured using the CLAS at Jefferson Lab for center-of-mass (CM) energies from threshold up to 2.84 GeV. Results are reported in 112 10-MeV wide CM energy bins, each subdivided into cos theta^omega_CM bins of width 0.1. These are the most precise and extensive omega photoproduction measurements to date. A number of prominent structures are clearly present in the data. Many of these
have not previously been observed due to limited statistics in earlier measurements. |
