${\Omega }_b$ semi-leptonic weak decays

Abstract

${\Omega }_b\to {\Omega }_c^{(\ast )}$ 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).
