Measurement of $\pi^{+}\pi^{-}$ Photoproduction In Double-Polarization Experiments using CLAS

Discussion will be given on an upcoming double-polarization experiment using a tagged-photon beam and the CLAS spectrometer at Jefferson Lab in Newport News, VA. Constituent quark models (CQMs) predict numerous baryon resonances that have not been experimentally verified and are thus ``missing.'' CQMs also predict a strong coupling of these states to $\rm\gamma p$ as well as to $\rm p\eta$ or $\Delta\pi$ making photoproduction experiments a promising method to find these missing resonances. Previous analyses show that constraints provided by polarization observables are important because analyses of unpolarized data often result in ambiguous solutions. A linearly- and circularly-polarized photon beam will be incident on a polarized butanol target in Hall B's CLAS detector. This detector allows for the use of a longitudinally- or transversely-polarized frozen spin target (FROST) giving rise to nine double-polarization observables in $\pi^+\pi^-$ production. Studies of the sensitivity of these observables to baryon resonances will be discussed.
