Formation of parity-nonconserving nuclear forces in the standard model SU(2)/sub L/ x U(1) x SU(3)/sub c/
A unified scheme for investigating weak meson--nucleon vertices defining parity-nonconserving nuclear forces has been suggested in the paper by Desplanques, Donoghue, Holstein (Ann. Phys. (N. Y.) 124 (1980), 449). Reasonable bounds for the values of constants h/sub M/ were found and the so-called ''best values'' for them were chosen in that paper. Continuing these investigations we propose a self-consistent approach based on the standard SU(2)/sub L/ x U(1) x SU(3)/sub c/ theory for the calculation of all contributions to h/sub M/. This allows us to analyse the role of each component of the standard model: charged and neutral currents, a color interactions. We have obtained h/sub ..pi../ = 1/3h/sup b.v//sub ..pi../ and h/sub rho//sub ,//sub ..omega../ which in th whole agree with h/sup b.v//sub rho/. The values obtained for h/sub M/ are stated to agree with the available experimental data, and some future experiments are discussed.
