Abstract

The parity nonconserving longitudinal analyzing power is calculated in elastic scattering at the energies below the approximate inelastic region T _lab = 350 MeV. The short-ranged heavy meson ρ and ω exchanges as well as the longer-ranged 2π exchanges (with and without intermediate NΔ configurations) are considered as the mediators of the parity nonconserving interactions. The DDH “best” coupling values are used as the parity nonconserving meson-NN couplings. Also three different parity nonconserving two-pion exchange potentials by various authors are compared.
