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.

Transition Matrix Elements

The radiative decays of heavy mesons are studied in the heavy quark symmetry formalism. Assuming the traditional picture of photon emission by the confined quark or antiquark, we obtain the transition matrix elements for the heavy quark current sector. For the light quark sector we employ the ISGW quark model. The results obtained agree reasonably well with other estimations.
