This paper investigates the static properties and semileptonic decay processes of doubly heavy baryons using a non-relativistic quark model, providing mass, magnetic moments, and decay predictions consistent with existing theories.

Contribution

It introduces a phenomenological potential model to calculate properties of doubly heavy baryons and employs a universal Isgur-Wise function for decay form factors in the heavy quark limit.

Findings

Calculated ground-state masses and magnetic moments of doubly heavy baryons.

Predicted semileptonic decay widths and branching ratios.

Results agree with other theoretical models.

Abstract

The static properties and semileptonic decays of ground-state doubly heavy baryons are studied working in the framework of a non-relativistic quark model. Using a phenomenological potential model, we calculate the ground-state masses and magnetic moments of doubly heavy $ \Omega $ and $ \Xi $ baryons. In the heavy quark limit, we introduce a simple form of the universal Isgur-Wise function used as the transition form factor and then investigate the exclusive $ b \rightarrow c $ semileptonic decay widths and branching ratios for $ \frac{1}{2}\rightarrow \frac{1}{2} $ baryon transitions. Our obtained results are in agreement with other theoretical predictions.
