Relative probabilities for decays of hadrons containing b quarks in the combinatorial quark counting model

In the framework of quark combinatorial counting model at finite energies, predictions for relative probabilities of few-particle hadronic decay channels of γ-, B-mesons and Λsub(b)sup(0)-baryon are obtained. The B0-meson and Λsub(b)sup(0)-baryon decays are considered with account of both the spectator and annihilation decay mechanisms. The importance of investigating such B0 and Λsub(b)sup(0) decay channels, which are impossible through a spectatorial decay mechanism, as well as channels of B meson and Λsub(b)sup(0)-baryon decays without formation of charmed hadrons in the finite state, is noted. Experimental investigation into the decay of heavy hadrons containing b(anti b)-quarks is the cause of the near future. Preliminary estimates of branchings of the most interesting channels appear necessary in this connection for the projecting appropriate experiments and during their interpretation
