摘要：
Omega(b) -> Omega(()(c)*()) semileptonic 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 heavy quark effective theory.
