Quantum groups and Cabibbo mixing

Abstract:
Treating the issue of hadron masses on the base of quantum groups U_q(u_n) 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.
