Semileptonic hyperon decays in the Skyrme model with bound kaon approach to strangeness

The vector and axial-vector coupling constants of the semileptonic weak decay of hyperons are calculated with the bound kaon approach to strangeness in the Skyrme model proposed by Callan and Klebanov. The values of the gA/gV ratios for the strangeness-changing processes are within the same level as in the strangenes-conserving processes. We however see that the constants gV deviate largely from those in the SU(3) symmetric model. A peculiar Nc dependence of the currents is also discussed. (orig.)
