Description
The strong coupling constants of the heavy baryons to light pseudoscalar and vector mesons are calculated in light cone QCD sum rules. In particular, using the general form of the interpolating currents for the heavy baryons and distribution amplitudes of mesons as well as different symmetry arguments, all amplitudes in each class of transitions are written in terms of only one universal invariant function. Using the values obtained for the strong coupling constants, we also evaluate the decay rates of the corresponding strong transitions. A comparison of the obtained results with the existing predictions of the other nonperturbative approaches as well as experimental data is also made.
