Prospects for measurements of parity-violatingphotoproduction of

I address the experimental feasibility of two measurements related to the photoproduction of pions, in the context of the G0 experiment. The first involves an extraction of the parity-violating pion-nucleon coupling constant $h_{\pi NN}^{(1)}$ via a measurement of parity-violating threshold pion photoproduction. The second involves an extraction of $d_\Delta$, which parameterizes parity-violating photoproduction of pions on the $\Delta$-resonance. The second process might have an anomalously large asymmetry, from a model based on hyperon decays
