摘要：
Exclusive nonleptonic decays of bottom baryons to charm baryons and pseudoscalar light mesons are analyzed within a relativistic three-quark model. We include factorizing as well as nonfactorizing contributions to the decay amplitudes. The total contribution of the nonfactorizing diagrams amount to 30% of the factorizing contributions in amplitude. We present detailed predictions for rates and asymmetry parameters.
