Abstract
Chiral perturbation theory is used in order to analyze the process and results are compared with the PCAC (partial conservation of axial-vector current) and Low-theorem analyses of Fearing, Fischbach, and Smith. These predictions are found to be consistent with but much stronger than those of the earlier analysis, and verification of these results can be used as a test of chiral symmetry.
