Parity-Nonconserving Asymmetry In Proton-Proton Scattering

Abstract

The effects of a weak force between nucleons can be studied directly through the scattering of longitudinally polarized nucleons on nucleons. We use distorted-wave theory to predict the dependence of the differential and total cross sections on the helicity of longitudinally polarized protons for elastic proton-proton scattering up to \ensuremath{\sim}300 MeV. The weak force used is parametrized by ${\ensuremath{\rho}}^{0}$, ${\ensuremath{\omega}}^{0}$, and two-pion exchanges.
