英文摘要	In this work, we calculate the branching ratios of the color-allowed two-body nonleptonic decays of the bottom baryons, which include the Xi(b) -> Xi(())(c) and Omega(b) ->Omega(c) weak transitions by emitting a pseudoscalar meson (pi-, K-, D-, and D-s) or a vector meson (pi(-), K-, D-, and D-s(-)). For achieving this aim, we adopt the three-body light-front quark model with the support of hadron spectroscopy, where the spatial wave functions of these heavy baryons involved in these weak decays are obtained by a semirelativistic potential model associated with the Gaussian expansion method. Our results show that these decays with the pi(-), rho(-), and D(s)(()-)emitted mode have considerable widths, which could be accessible at the ongoing LHCb and Belle II experiments.
