摘要：

We present a detailed description of semileptonic decays of baryons LAMBDA(b)0 --> LAMBDA(c)+ and SIGMA(b)+ --> SIGMA(c)++ in the framework of the quark confinement model, which is a relativistic quark model based on definite asumptions about hadronization and confinement of light quarks. Weak form factors, decay rates and differential distributions of semileptonic decays LAMBDA(b)0 --> LAMBDA(c)+ and SIGMA(b)+ --> SIGMA(c)++ are calculated. The heavy quark limit m(Q) --> infinity (Isgur-Wise symmetry) is also examined.
