Abstract

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, A_y, by these models. Our conclusion is that a quantitative chiral two-nucleon potential does not resolve the Nd A_y puzzle (when only two-body forces are included).
