Description

Asub(π)=A(n → π-p) parity-violating amplitude is considered. Within the field-theoretical approach it is shown that cononical ETC-part (where ETC is the equal time commutator) of Asub(π) corresponds to nonfactorizing (NF) diagrams. Asub(π)sup(NF) may be calculated for the total effective Hamiltonian in SU(2)sub(L) x U(1) x SU(3)sub(C) theory via the SU(3) sum rule and is very sensitive to the behaviour of running QCD constant asub(s)(μ) at μ < or approximately msub(c) (msub(c) is mass of c-quark). It is argued that the contribution of factorizing diagrams into Asub(π) is negligible
