Axial-vector constants and semileptonic decays — •H.-Ch. Kim, M.V. Polyakov, M. Praszałowicz, and K. Goeke — Institut für Theoretische Physik II, Ruhr-Universität Bochum, D-44780 Bochum Germany
We have investigated the axial-vector constants, based on a “model-independent” way within the chiral quark-soliton model (χQSM). The χQSM provides the relations between the semileptonic decay constants and axial-vector ones. Employing the experimental data of the semileptonic decay constants g1/f1, we have obtained the axial-vector constants gA(0,3,8).
