Heavy-light baryonic mass splittings from the lattice
We present lattice estimates of the mass of the heavy-light baryons \Lambda_b and \Xi_b obtained using propagating heavy quarks. For \Lambda_b our result is M_{\Lambda_b}=5.728 \pm 0.144 \pm 0.018 GeV, after extrapolation to the continuum limit and in the quenched approximation.
