Abstract
Spin observables in the photoproduction of the are explored for the purpose of determining the parity of the . Based on reflection symmetry in the scattering plane, we show that certain spin observables in the photoproduction of the can be related directly to its parity. We also show that measurements of both the target nucleon asymmetry and the polarization may be useful in determining the parity of in a model-independent way. Furthermore, we show that no combination of spin observables involving only the polarization of the photon and∕or nucleon in the initial state can determine the parity of unambiguously.
