Our findings reveal that most branching fractions calculated in this study, such as ${\\cal B}(\\Omega_b^-\\to\\Xi^- D^0,\\Xi^{-}D^{*0})$, can be ten to one hundred times larger than those reported in previous calculations. Additionally, we interpret the ratio ${\\cal B}(\\Omega_b^-\\to\\Omega^- J/\\psi)/{\\cal B}(\\Omega_b^-\\to\\Omega^- \\eta_c)\\simeq 3.4$ within the helicity framework.
