摘要：

We construct to all orders in the pion field and to one power of pion momentum the most general lagrangian for parity-violating pion-nucleon interactions that can arise from weak interactions. In particular, we show that in addition to the previously discussed P-violating piNN vertex, there are independent pipiNN, and pigammaNN interactions. All three may be relevant for nuclear and atomic parity-violation experiments, as well as P-violating elastic nucleon scattering. We give numerical estimates for the interactions, and show that there is reason to believe that the Z0-induced strange-quark operator (sgamma(mu)gamma5sBAR)(ugamma(mu)uBAR-dgamma(mu)dBAR) contributes significantly in the DELTAI = 1 channel.
