| Abstract: | Using the consistency requirements arising from the Coleman-Glashow null result for ‘tadpole’-type symmetry-breaking, we obtain
a simple method of accounting for the SU(3) symmetry-breaking at theBBP-vertex, without introducing any new parameters. The results obtained are in excellent agreement with the available numbers.
We extend the analysis to the charmed baryon couplings in order to accommodate SU(4)-breaking. |
