摘要：

The currently available experimental data on the K±p forward scattering amplitudes are analyzed by three different methods: a discrepancy-function method, the Haber-Schaim linear extrapolation method, and a method based on a once-subtracted dispersion relation. Substantially more data are used than in previous analyses. The results of the three methods are found to be in good qualitative agreement. Predictions are obtained for the value of the effective KNY coupling constant and for the real parts of the K±p forward scattering amplitudes over a wide range of energies. © 1979.
