Abstract
The proton-proton parity-violating analyzing power is calculated for laboratory energies up to 1200 MeV using relativistic strong and weak potentials derived consistently from meson field theory. We calculate the parity-violating t-matrix elements with strong distortions generated by the static momentum-space one-boson-exchange Bonn potential. The weak, parity-violating potential, which is derived from parity-violating rho and omega exchanges, employs Desplanques-Donoghue-Holstein weak coupling parameters and Bonn-model coupling parameters and form factors. Below 200 MeV, the results differ very little from a nonrelativistic calculation using the r-space Bonn potential, but at 800 MeV, the analyzing power increases by 44 percent. A calculation with nonstatic, energy-dependent potentials is included for energies below pion-production threshold. The result is larger than for the static calculation, by an amount increasing from 3 percent at 15 MeV to 14 percent at 300 MeV.
