Abstract

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→ Λ_c⁺γ)= 60.7± 1.5 KeV, Γ(Ξ^'+_c→ Ξ_c⁺γ) = 12.7± 1.5 KeV, Γ(Λ_c1(2593)→Λ_c⁺γ)=104.3± 1.3 KeV.
