Abstract.

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.
