Quantum groups and Cabibbo mixing

Treating the issue of hadron masses on the base of quantum groups Uq(un) used for the role of flavor symmetries of hadrons suggests, at least in the case of baryons, a direct connection of deformation parameter q with the Cabibbo angle. We discuss a number of different manifestations of the Cabibbo mixing (including possible novel ones) implied by such connection.
