摘要：
Parity nonconserving two-pion exchange in elastic ¯pp scattering is investigated in the presence of phenomenological strong distortions in various models. Parity violation is included in the NNπ vertex considering NN and NΔ(1232) intermediate states in box and crossed box diagrams. Using the derived parity nonconserving two-pion exchange potential we calculate the longitudinal analyzing power ¯L in elastic pp scattering. The predicted effect is of the same order as vector meson exchanges.
