  It is shown that for the effective Lagrangian with factorization ansatz
considered here, the two body hadronic decay $\mathcal{B}_{b}(\frac{1}{2}^+)
\to \mathcal{B}(\frac{1}{2}^{+},\; \frac{3}{2}^{+}) + V$, for
$\mathcal{B}_{b}(\frac{1}{2}^{+})$ belonging to the representation $\bar{3}$,
only allowed decay channel is $\mathcal{B}_{b}(\frac{1}{2}^+) \to
\mathcal{B}(\frac{1}{2}^{+})+ V$, where $\mathcal{B}(\frac{1}{2}^{+})$ belongs
to the representation $8$ of $SU(3)$. However, for
$\mathcal{B}_{b}(\frac{1}{2}^{+})$ belonging to the sextet representation $6$,
the allowed decay channels are $\mathcal{B}_{b}(\frac{1}{2}^+) \to
\mathcal{B}(\frac{1}{2}^{+},\; \frac{3}{2}^{+}) + V$, where
$\mathcal{B}(\frac{1}{2}^{+})$ and $\mathcal{B}(\frac{3}{2}^{+})$ belongs to
the octet representation $8^{\prime}$ and the decuplet $10$ of $SU(3)$,
respectively. The decay channel $\mathcal{B}_{b}(\frac{1}{2}^+) \to
\mathcal{B}(\frac{1}{2}^{+}) + V$ is analyzed in detail. The decay rate
($\Gamma$) and the asymmetry parameters $\alpha\;, \alpha^{\prime}\;, \beta\;,
\gamma$ and $\gamma^{\prime}$ are expressed in terms of four amplitudes. In
particular for the decay $\Lambda_b \to \Lambda + J/\psi$ it is shown that
within the factorization framework, using heavy quark spin symmetry, the decay
rate and the asymmetry parameters can be expressed in terms of two form factors
$F_1$ and $F_{2}/F_{1}$, which are to be evaluated in some model. For other
heavy quarks belonging to the triplet and sextet representation, the results
can be easily obtained by using $SU(3)$ symmetry and phase space factor.
Finally, the decay $\Omega_{b}^{-} \to \Omega^{-} + J/\psi$ is analyzed within
the factorization framework. It is shown that the asymmetry parameter $\alpha$
in this particular decay is zero. The branching ratio obtained in the first
approximation is compared with the experimental value.
