One-photon transitions between heavy baryons in a relativistic three-quark model

We study one-photon transitions between heavy baryon states in the framework of a relativistic three-quark model. We calculate the one-photon transition rates for ground-state to ground-state transitions and for some specific excited state to ground-state transitions. Our rate predictions for the most important transitions are: Γ(Σ+c→Λc+γ)=60.7±1.5 keV, Γ(Ξ′+c→Ξc+γ)=12.7±1.5 keV, Γ(Λc1(2593)→Λc+γ)=104.3±1.3 keV.
