Parity nonconserving nucleon-nucleon scattering (one-boson-exchange) in the weinberg-salam model

In the present paper we discuss the implications of the Weinberg-Salam model of weak interactions for parity non-conserving nucleon-nucleon scattering. The one-boson-exchange nucleon-nucleon potentials are determined by the use of the factorization method and current algebra. The effect of the neutral hadronic currents is to enhance both the pion contribution $\text{(Δ}\text{I}\text{?}\text{=1)}$ and the vector meson contribution (ΔI=0, (2))). The Weinberg-Salam model is consistent with the recent experiment on ¹⁹F and leads to a sizable measurable polarization effect in the transition 0^-, 0(1.08 MeV) to the ground state of ¹⁸F, namely, P ～ 5 × 10^?3.
