Query: Chiral Symmetry and the Parity-Violating $NN\pi$ Yukawa Coupling   We construct the complete SU(2) parity-violating (PV) $\pi, N, \Delta$
interaction Lagrangian with one derivative, and calculate the chiral
corrections to the PV Yukawa $NN\pi$ coupling constant $h_\pi$ through ${\cal
O}(1/\Lambda_\chi^3)$ in the leading order of heavy baryon expansion. We
discuss the relationship between the renormalized $\hpi$, the measured value of
$\hpi$, and the corresponding quantity calculated microscopically from the
Standard Model four-quark PV interaction.
