Title: CLAS+FROST: new generation of photoproduction experiments at Jefferson Lab.
Keywords: photoproduction, dououble polarization
Abstract:
A large part of the experimental program in Hall B of the Jefferson Lab is dedicated to baryon spectroscopy. Photoprodcution experiments are essential part of this program. CEBAF Large Acceptance Spectrometer (CLAS) and availability of circularly and linearly polarized tagged photon beams provide unique conditions for this type of experiments. Recent addition of the Frozen Spin Target (FROST) gives a remarkable opportunity to measure double and triple polarization observables for different pseudo-scalar meson photoproduction processes. For the first time, a complete or nearly complete experiment becomes possible and will allow model independent extraction of the reaction amplitude. An overview of the experiment and its current status will be presented. |
