Abstrakt: We calculate the s term with the assumption of Weinberg's smoothness hypothesis and thegA axial coupling constant by using the most recent experimental data and we give a realistic estimation of the errors. We find for sNNKK values ranging from 493 to 687 MeV, depending on the value assumed forgS2/4p, but the statistical uncertainty on it is of about 717 MeV.
