Parity Violation in gamma proton Compton Scattering

Nuclear Theory 2009-10-31 v3 High Energy Physics - Phenomenology

Abstract

A measurement of parity-violating spin-dependent gamma proton Compton scattering will provide a theoretically clean determination of the parity-violating pion-nucleon coupling constant hπNN(1)h_{\pi NN}^{(1)}. We calculate the leading parity-violating amplitude arising from one-loop pion graphs in chiral perturbation theory. An asymmetry of ~5 10^{-8} is estimated for Compton scattering of 100 MeV photons.
