English Abstract

This study is divided into two parts. In the first part, the two-body radiative decays of the b-flavored baryons ar analyzed in the framework of the nonrelativistic quark model and perturbation theory. With the obtained decay widths, we give an estimate for the mean lifetimes of the states ∈0¹, ∈¹, and Ω*-. As for the second part, the two-body nonleptonic decays of bottom baryons containing a single b-quark are investigated in the factorization scheme, treating the color-matching parameter ε as a free parameter. The nonrelativistic quark model is used to calculate the weakcurrent baryonic form factors at s = m²x, where X is either a pseudoscalar, a vector or an axial vector meson thereby taking into account the recoil correction. The obtained decay rates are not very sensitive to ε, if 0 < ε < 0.5 as suggested by two-body B meson decays.
