The effect of the long-range confining potential on the two gluino bound states has been studied in a particular potential model. Some useful inequalities for the value of the wave function at the origin, [Formula: see text] have been derived for a more general class of potentials. The results will be useful for estimating various decay widths.

Central Forces

Relativistic corrections including the central forces (up to 1/m2) are calculated numerically for baryon systems. The χ2 analyses suggest the 2-body confining potential in the baryons to be predominantly of vector nature. Baryon masses with heavy flavor (c, b) are predicted and reproduced well.

The decay rates of charmonium ([Formula: see text]bound states) are studied in the context of a simple quark confining potential model proposed earlier. In particular, we calculate the leptonic and hadronic decay rates of the S-states and a comparison is made with the available experimental data. The model prescriptions are then applied to predict the decay rates of the P-states of charmonium which are found to be consistent with other theoretical expectations.

Relativistic Potential

Weak electric and magnetic form factors for semileptonic transitions of baryons are calculated in a relativistic quark model with the independent quark confining potential of the form [Formula: see text], a > 0. The values obtained for g2/g1 for various decay modes compare well with the nonrelativistic results of Donoghue and Holstein. The values of g1/f1 extracted from our model calculations of f2/f1 in the Cabibbo limit are not very different from those of the experiment. The values calculated for f2/f1 for various semileptonic transitions also agree well with those of the MIT bag model. The SU(3) symmetry breaking does not degenerate appreciable departures in f2/f1 values from the corresponding Cabibbo values.
