One-Photon Transitions between Heavy Baryons in a Relativistic Three-Quark Model

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}\to Λ_c^+γ)= 60.7\pm 1.5 $ KeV, $Γ(Ξ^{'+}_{c}\to Ξ_c^+γ) = 12.7\pm 1.5$ KeV, $Γ(Λ_{c1}(2593)\toΛ_c^+γ)=104.3\pm 1.3$ KeV.
