Axial-vector meson emitting weak nonleptonic decays of bottom baryons

Abstract

We investigate the two-body weak nonleptonic decays of ${\ensuremath{\Lambda}}_{b}^{0}$, ${\ensuremath{\Xi}}_{b}^{0}$, and ${\ensuremath{\Xi}}_{b}^{\ensuremath{-}}$ into the octet baryons (${J}^{P}=1/{2}^{+}$) and axial-vector mesons (${J}^{P}={1}^{+}$) employing the factorization scheme and obtain their branching ratios and asymmetry parameters.
