Book Description
Electro- and photoproduction of w(783) from a proton target have been measured in the CLAS detector at the Thomas Jefferson National Accelerator Facility in Newport News VA. The photoproduction data were taken over a photon energy range from 0.5 to 2.3 GeV, while the electroproduction data was obtained over a W range of 1.8-2.5 GeV/c2. Preliminary acceptance corrected center-of-mass angular distributions have been examined for both data sets.

Book Description
The focus of this analysis is photoproduced ? and ?' mesons. The data were obtained in Hall B at Jefferson Lab using a photon beam at an endpoint energy of 4.016 GeV in the spring and summer of 2004. The Hall B photon tagging system and the CLAS spectrometer were used to collect the data. From this data, and in the course of analysis of the N? and N?' systems, measurements were made of the differential cross sections for ? and ?' photoproduction. The differential cross section measurements for the ? improve the statistics and slightly improve the kinematic range for world data. The results for the ?' represents an almost entirely new dataset which will allow for further analysis of the ?' meson. The results of this measurement for the ?' extend the statistics and kinematic range of world data dramatically.

Book Description
A large part of the experimental program in Hall B of the Jefferson Lab is dedicated to baryon spectroscopy. Meson photoproduction experiments are essential part of this program. CEBAF Large Acceptance Spectrometer (CLAS) and availability of circularly and linearly polarized tagged photon beams in combination with longitudinally and transversely polarized frozen spin targets provide unique conditions for this type of experiments. For the first time, a complete or nearly complete measurement became possible and will allow model independent extraction of the reaction amplitude. The measurements were complete with both proton and deuteron targets. An overview of the collected experimental data will be presented.

Book Description
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.
