abstract
We analyze strong one-pion and radiative one-photon decays of heavy flavored baryons within a relativistic three-quark model. Employing the same parameters 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 available and with the results of other model calculations.

Radiative decays of $P$-wave charmed baryons in the $SU(3)$ flavor $\bf6_F$ representation
The authors predict radiative decay widths for all P-wave charmed baryons in the 6F representation, and propose Omega_c gamma channels as the best route to identify the excited Omega_c states seen at LHCb.
