We analyze strong one-pion and radiative one-photon decays of heavy flavore
d baryons within a relativistic three-quark model. Employing the same param
eters as were used for the description of the semileptonic decays of heavy
baryons, we calculate the couplings of one-pion and one-photon transitions
of both ground and excited heavy baryon states. We predict the decay rates
for all relevant decay modes and compare them with experimental data when a
vailable and with the results of other model calculations. [S0556-2821(99)0
