Chiral symmetry and the parity-violating NN pi Yukawa coupling - art. no. 033006

We construct the complete SU(2) parity-violating (PV) pi ,N,Delta. interact ion Lagrangian with one derivative, and calculate the chiral corrections to the PV Yukawa NNpi coupling constant h(pi) through O(1/Lambda (3)(chi)) in the leading order of heavy baryon expansion. We discuss the relationship b etween the renormalized h(pi), the measured value of h(pi), and the corresp onding quantity calculated microscopically from the standard model four-qua rk PV interaction. We observe that the renormalized h(pi) depends strongly on a number of a priori unknown parameters in the PV effective Lagrangian.
