Two-body nonleptonic decays of $\Omega_{b}\rightarrow \Omega_{c}$ beyond tree level

We study the nonleptonic decays of $\Omega_{b}\rightarrow\Omega_{c} P (V)$ with eight pseudoscalar and vector mesons using the naive factorization approach. We analyze all relevant topologies (the tree-level, color-suppressed, and penguin) of these decays and calculate the decay amplitude for each separately. We determine the decay rates, branching ratios and compare our results with those from other theoretical predictions. The results obtained may be useful for the analysis of the related data in both ongoing and future experiments.
