We perform a lattice study of heavy baryons, containing one (Λb) or two b-quarks Ξb. Using the quenched approximation we obtain for the mass of Λb, MΛb = 5.728 ± 0.144 ± 0.018 GeV. The mass splitting between the λb 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. © 1994.
