Confining Potential Mode in Baryons Spectrum

Based on the flux tube model, the effects of the confining potentials of different configurations, namely theΔ-type and the Y-type, on the spectra of baryons are studied on SU_SF(6) basis. The baryon spectra are obtained in a unified manner. Our result shows that by employing either the Δ-mode or the Y-mode confining potential, one can achieve reasonable baryon spectra. TheΔ-mode may be mostly effective for the short- and medium-distances, while the Y-mode may offer more contributions tothe spectra for long-distances. Although the binding energies inbaryon spectra may deviate by a few to several tens MeV for different modes, it is hard to determine either one to be dominant by simply evaluating the baryon spectra. One may need to invokethe baryon decay process to make further judgement.
