Parity-violating interaction effects: The longitudinal asymmetry inppelastic scattering

The proton-proton parity-violating longitudinal asymmetry is calculated in the laboratory-energy range 0–350 MeV, using a number of different, latest-generation strong-interaction potentials—Argonne $v_{18},$ Bonn-2000, and Nijmegen-I—in combination with a weak-interaction potential consisting of $\rho$- and $\omega$-meson exchanges—the model known as DDH. The complete scattering problem in the presence of parity conserving, including Coulomb, and parity-violating potentials is solved in both configuration and momentum space. The predicted parity-violating asymmetries are found to be only weakly dependent upon the input strong-interaction potential adopted in the calculation. Values for the $\rho$- and $\omega$-meson weak coupling constants $h_{\rho }^{\mathrm{pp}}$ and $h_{\omega }^{\mathrm{pp}}$ are determined by reproducing the measured asymmetries at 13.6 MeV, 45 MeV, and 221 MeV.
