Three-quark forces and the role of meson exchanges in weak NN interaction

Creators

Description

The contribution of weak three-quark forces involving meson exchanges to the longitudinal analyzing power AL in the low-energy pp-scattering is calculated. The nonrelativistic potential model is used for the desorption of strong quark interactions while their weak coupling is described by the Weinberg-Salam lagrangian. The dominant mechanism of parity violation in the NN system (provided the one-pion exchange is forbidden by selection rules) is the contact interaction of quarks. 17 refs.; 3 figs
