Abstract

Polarized beam gamma p Compton scattering provides a theoretically clean way to extract the isovector parity violating pion-nucleon coupling constant hπNN(1). This channel is more tractable experimentally than the recently proposed extraction of hπNN(1) from the Bedaque-Savage process --- polarized target gamma p compton scattering. The leading parity violating effect is calculated using Heavy Baryon Chiral Perturbation Theory. The size of the asymmetry is estimated to be ~ 4 10-8 for 120 MeV photon energy.
