Abstract: We investigate the nonleptonic two-body weak decays of the single bottom baryon Ωb* into Ωc*P(V) final states within the factorization framework. Employing this framework and incorporating the contributions from the current-current operators, we compute the tree-level decay amplitudes and decay widths of the Ωb*→Ωc*P(V) processes in terms of the Ωb*→Ωc* transition form factors. Here, P and V denote pseudoscalar and vector mesons, respectively. Using the form factors obtained in our previous work, we evaluate the numerical values of the decay widths for the dominant nonleptonic weak channels. This study complements our previous analysis of the semileptonic weak transitions Ωb*→Ωc*ℓν¯ℓ reported in Ref. [1], thereby providing a detailed investigation of dominant Ωb*→Ωc* weak decays of the Ωb* baryon.
