Radiative decays of heavy baryons with heavy quark symmetry

Abstract

The decay widths for the radiative decays of heavy baryons are calculated in the the heavy quark effective theory. Introducing the interpolating fields for heavy baryons we obtain the transition matrix elements and the corresponding decay widths. Considering the SU(6) flavor-spin wave fuctions for heavy baryons, the coupling constants are calculated in the nonrelativistic quark model. Since the masses of the heavy baryons are not available, we have taken the predicted bag model masses. We find our results are quite different form the of the heavy quark bag model calculations.
