Abstract.
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 \(\frac{\pi}{14}\), in terms of the deformation parameter q and spin parity JP of the baryons is obtained.
