[en] The quantum group SU_q(3) = U_q(su(3)) is taken as a baryon flavor symmetry. Accounting for electromagnetic contributions to baryons masses up to zeroth order, new charge specific q-deformed octet and decuplet baryon mass formulas are obtained. These new mass relations have errors of only 0.02% and 0.08%, respectively, a factor of 20 reduction compared to the standard Gell-Mann-Okubo mass formulas. A new relation between the octet and decuplet baryon masses that is accurate to 1.2% is derived. An explicit formula for the Cabibbo angle, taken to be (π)/(14), in terms of the deformation parameter q and spin parity J"P of the baryons is obtained. (orig.)
