Measurements of the Polarization Observables Is and Ic for γ→p→pπ+π- using the CLAS Spectrometer

Model predictions regarding the excited baryon spectrum provided by Constituent Quark Models show good agreement with experimental measurements in the low-energy region less than ≅1.8 GeV. The mass region above ≅1.8 GeV, however, contains many resonances which are predicted to exist by these models but have not been experimentally verified. The analysis of a double meson final state using linearly polarized photoproduction data allows access to two polarization observables, Is and Ic(also known as the beam asymmetry Σ for a single meson final state). It has been shown that measurements of these polarizaton observables can provide insight into this missing resonance problem. This analysis was carried out on data taken from the CLAS-g8b data run period conducted at Jefferson Lab in Newport News, Virginia. The analysis of this data and preliminary measurements of these obsevables will be dicussed.
