Linking the parameters of diquark-quark model to the Cabibbo angle

From two different modifications of the Gell-Mann-Okubo mass relation for (1/2)^+ baryons: the first one given by a version of diquark-quark model and the second one being the optimal mass sum rule obtained by using quantum groups U_q(su_n) for the role of hadronic flavor symmetries, we find direct connection of the mass parameters of the diquark-quark model of Lichtenberg, Tassie and Keleman to the (proper value of) q-parameter and then to the Cabibbo angle.
