The proton-proton parity-violating analyzing power is calculated at laboratory energies up to 1000 MeV using a parity-violating weak meson-exchange potential with form factors and coupling constants consistent with the nonrelativistic Bonn potential. A real distorted-wave Born-approximation formulation of the weak scattering amplitude is introduced using real standing waves with distortions by Coulomb and strong interactions. This formulation includes a new and simplified expression for the S matrix in terms of strong and real weak amplitudes. The form-factor contributions to the weak potential significantly reduce the overall magnitude of the analyzing power, but do not qualitatively affect the relative energy or angular dependence. Results using, alternatively, Paris, Reid soft-core, Hamada-Johnston, and pure Coulomb distorted waves with the same weak potential are compared. The angular and total analyzing powers are calculated with long-range Coulomb contributions for scattering and transmission experiments. The long-range Coulomb effects can be removed, leading to a reduced analyzing power A-italic-circumflex that depends only on short-range forces.
