We analyze the results by chiral NN models for the two-nucleon system and
calculate the predictions for the nucleon vector analyzing power of elastic
nucleon-deuteron (Nd) scattering, Ay, by these models. Our conclusion is that a
QUANTITATIVE chiral two-nucleon potential does not resolve the Nd Ay puzzle
(when only two-body forces are included).Comment: 19 pages RevTex including 8 figure
