We calculate the decay width for [Formula: see text] in the framework of a non-relativistic quark (NRQ) model of heavy baryons where the light quarks play the role of spectators. Our calculation does not make an explicit use of the heavy quark symmetry. The branching ratio for the above process as calculated here agrees reasonably well with the experimental value.

Heavy Quark Limit

We propose a simple model to describe the semileptonic weak decays among heavy baryons in the heavy quark limit in a unified way. The current matrix elements of the heavy baryons, with spin-0 light diquark, are evaluated to give the ω-dependence of the form factors. The numerical values are also calculated and the branching ratio for [Formula: see text] is consequently obtained in the range (4.9–15.3)%.

Hadron spectra and other properties of quark systems are studied in the framework of a non-relativistic spinindependent phenomenological model. The chosen confining potential is harmonic, which allowed us to obtain analytical solutions for both meson and baryon (of equal constituent quarks) spectra. The introduced parameters are fixed from the low-lying levels of heavy quark mesons. The requirement of flavor independence is imposed, and it restricts the possible choices of inter-quark potentials. The hyper-spherical coordinates are considered for the solution of the three-body problem.
