Mass Spectra of Doubly Heavy Strange baryons ${\Omega }_{Q{Q}^{{}^{\prime }}}$ and their Decay properties

Abstract

This study investigates baryons ${\Omega }_{cc}$, ${\Omega }_{bc}$ and ${\Omega }_{bb}$ composed of two heavy quarks and one strange light quark, focusing on their radial and excited state mass spectra. We employ the Hyper Central Constituent Quark Model (hCQM), incorporating higher-order corrections, including second-order mass corrections with explicit consideration of spin-dependent interactions. This approach improves the accuracy of spin splitting predictions. Additionally, we present a detailed comparison between our predicted resonance masses and those obtained from other theoretical models. We assign all possible spin-parity quantum numbers, offering a comprehensive understanding of the properties of doubly heavy baryons. Furthermore, we compute key properties such as magnetic moments, transition magnetic moments, radiative decay widths. The analysis also reveals a linear behavior in the Regge trajectories.
