Abstract
The formalism of current algebra and partially conserved axial-vector current (PCAC) hypothesis is applied to study the Kp and πp interaction processes involving hyperons and one or two soft pions. The differential cross-sections for the processes are normalized to the differential cross-sections for the corresponding processes without the soft pions. Theoretical predictions for the ratio of cross-sections at various laboratory meson momenta are compared with the existing experimental data. Angular distributions are also given for different incoming meson momenta
