pi-NN Coupling Constants from NN Elastic Data between 210 and 800 Mev

Abstract

High partial waves for $pp$ and $np$ elastic scattering are examined critically from 210 to 800 MeV. Non-OPE contributions are compared with predictions from theory. There are some discrepancies, but sufficient agreement that values of the $\pi NN$ coupling constants $g_0^2$ for ${\pi }^0$ exchange and $g_c^2$ for charged $\pi$ exchange can be derived. Results are $g_0^2=13.91\pm 0.13\pm 0.07$ and $g_c^2=13.69\pm 0.15\pm 0.24$, where the first error is statistical and the second is an estimate of the likely systematic error, arising mostly from uncertainties in the normalisation of total cross sections and $d\sigma /d\Omega$.
