Sažetak
This report is an attempt to explain both s- and p-wave nonleptonic hyperon decays by means of the QCD enhanced effective weak Hamiltonian supplemented by the SU(3) Skyrme model used to estimate nonperturbative matrix elements. The model has only one free parameter, namely, the Skyrme charge $e$, which is fixed through the experimental values of the octet-decuplet mass splitting $\Delta $ and the axial coupling constant $g_{A}$. Such a dynamical approach produces nonleptonic hyperon decay amplitudes that agree with experimental data reasonably well.
