摘要：

We perform a lattice study of heavy baryons, containing one (LAMBDA(b)) or two b-quarks (xi(b)). Using the quenched approximation we obtain for the mass of (LAMBDA(b), M(LAMBDA(b) = 5.728 +/- 0.144 +/- 0.018 GeV. The mass splitting between the LAMBDA(b) and the B-meson is found to increase by about 20% if the light quark mass is varied from the chiral limit to the strange quark mass.
