Abstract

Masses and decays of the baryons are considered. The entire spectroscopy of baryons containing u,d,s,c and b quacks is calculated using thefive quark masses and only four additional parameters describing the potential between the baryons. This potential is taken to be a short-range Coulomb potential together with a long-range linear potential modified by a harmonic-oscillator potential. Decays are studied using thequark pair creation model of Le Yaouane et. al. The pair strength gamma is replaced by (k) gamma. This and the meson radius are the only parameters used in the calculation of the decays. Overall, we have a useful model, employing a small number of parameters, yet capable of yielding a description of the baryons in good accord with experimental data.
