Conference paper


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 pionnucleon coupling constant h;π N N (1) via a measurement of parity-violating threshold pion photoproduction. The second involves an extraction of d Δ, 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.
