New results in omega photoproduction using high-statistics data obtained from CLAS at Jefferson Lab

OSTI ID:956319
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 energies, W, from threshold up to 2.84 GeV. An event-based partial wave analysis (PWA) has also been performed on the data. This analysis benefits from access to the world's first high precision spin density matrix element measurements, available to the event-based PWA through the decay distribution of omega-->pi+pi-pi0. Strong evidence has been found for nucleon resonance contributions.
