The proton-proton parity-violating longitudinal asymmetry is calculated in the lab-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 ρ-and ω-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 ρ-and ω-meson weak coupling constants h pp ρ and h pp ω are determined by reproducing the measured asymmetries at 13.6 MeV, 45 MeV, and 221 MeV. 21.30.+y, 25.40.Cm
