Mass Estimates of Ω bc Baryons in a Quark–Diquark Rotating String Model

We present a comprehensive study of the mass spectra of Ω bc baryons within a quark-diquark rotating string description. In this framework, the baryon is treated as a bottom-charm diquark core coupled to a strange quark via a relativistically rotating flux tube. Spin–dependent interactions are included to capture finer details of the spectrum. Employing this formulation, we predict the masses of both ground and excited Ω bc states. The ground-state predictions show close consistency with earlier theoretical work, supporting the validity of the model. Furthermore, we provide extensive results for radial and orbital excitations across the spectrum. These theoretical insights offer important guidance for experimental programs aimed at detecting Ω bc baryons, furnishing a timely benchmark for interpreting possible signals.
