Description

Rare nonleptonic Ω-→Ξ0(1530)π- decay branching ratio is estimated by means of the QCD enhanced effective weak Hamiltonian supplemented by the SU(3) Skyrme model used to estimate the nonperturbative matrix elements. Using mean values for experimental input parameters and the Skyrme charge e=4.75 we obtain the rate which is in good agreement with data
