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: $\Gamma ({\Sigma }_c^{+}\to {\Lambda }_c^{+}\gamma )=60.7\pm 1.5$ KeV, $\Gamma ({\Xi }_c^{{}^{\prime }+}\to {\Xi }_c^{+}\gamma )=12.7\pm 1.5$ KeV, $\Gamma ({\Lambda }_{c1}(2593)\to {\Lambda }_c^{+}\gamma )=104.3\pm 1.3$ KeV.
