By combining this analysis with a previous analysis of parity violation in proton-proton scattering, we are able to extract the size of the weak pion-nucleon coupling constant. The uncertainty is significant and dominated by the experimental error which is expected to be reduced soon.","authors_text":"A. Nogga, E. Epelbaum, J. de Vries, N. Kaiser, N. Li, Ulf-G.
