Strange particle contribution to the magnetic moment of the nucleon

The contribution of the strong hyperon-K-meson-nucleon interaction to the nucleon magnetic moment has been calculated, to the first order. In order to fit the observed values with pseudoscalar K-mesons one needs gπ2/4π = 9.6 and gKNY2/gπ2 = 0.06. If, however, the K-meson is assumed to be scalar, the last ratio becomes 0.016, which is perhaps too small, and gπ2/4π in this case is 11.3
