Semileptonic Decay Constants of Baryons in the Chiral Quark-Soliton Model — •Hyun-Chul Kim¹, Maxim V. Polyakov², and Klaus Goeke¹ — ¹Institute for Theoretical Physics II, Ruhr-University Bochum, D-44780 Bochum, Germany — ²Petersburg Nuclear Physics Institute, Gatchina, St. Petersburg 188350, Russia

The vector (f₁, f₂) and axial (g₁, g₂) constants for semileptonic decays are evaluated in the effective chiral quark-soliton model. The corrections linear in m_s and 1/N_c are taken into account. The possibly large deviations from the Cabibbo theory in various semileptonic decay modes are discussed.
