Abstract (EN): We investigate the semileptonic hyperon decays within the framework of the self-consistent SU(3) chiral quark-soliton model (χQSM). We take linear 1/Nc rotational as well as linear ms corrections into account and apply the symmetry conserving quantization. We present the results for the form factors f1(Q2), f2(Q2) and g1(Q2) in addition to the semileptonic decay constants of hyperons. We also have calculated the radii and dipole masses of these form factors for all relevant strangeness-conserving and strangeness-changing transitions.
