Query: $\Omega_b$ semi-leptonic weak decays   $\Omega_b \rightarrow \Omega_c^{(*)}$ semi-leptonic decays are studied in
details. Relevant helicity amplitudes are written down. Both unpolarized and
polarized $\Omega_b$ cases are considered. Decay angular distributions,
asymmetry parameters and semileptonic decay rates are calculated, with
numerical results using leading order results of the large $N_c$ and heavy
quark effective theory(HQET).
