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: $\hat{I}“(\hat{I}{\pounds }_c^{+}\to \hat{I}{›}_c^{+}{\hat{I}}^3)=60.7\pm 1.5$ KeV, $\hat{I}“(\hat{I}{ž}_c^{{}^{\prime }+}\to \hat{I}{ž}_c^{+}{\hat{I}}^3)=12.7\pm 1.5$ KeV, $\hat{I}“(\hat{I}{›}_{c1}(2593)\to \hat{I}{›}_c^{+}{\hat{I}}^3)=104.3\pm 1.3$ KeV.
