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^((1))_(πNN) via a measurement of parity-violating threshold pion photoproduction. The second involves an extraction of dΔ, which parameterizes parity-violating photoproduction of pions on the Δ-resonance. The second process might have an anomalously large asymmetry, from a model based on hyperon decays.
