      Beautiful baryons from lattice QCD 

      Alexandrou, Constantia; Borrelli, A.; Güsken, S.; Jegerlehner, F.; Schilling, K.; Siegert, G.; Sommer, R. (1994)
      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 ...

      Full QCD with the Lüscher local bosonic action 

      Alexandrou, Constantia; Borrelli, A.; de Forcrand, Ph; Galli, A.; Jegerlehner, F. (1995)
      We investigate Lüscher's method of including dynamical Wilson fermions in a lattice simulation of QCD with two quark flavours. We measure the accuracy of the approximation by comparing it with Hybrid Monte Carlo results ...

      Heavy-light baryonic mass splittings from the lattice 

      Alexandrou, Constantia; Borrelli, A.; Güsken, S.; Jegerlehner, F.; Schilling, K.; Siegert, G.; Sommer, R. (1995)
      We present here lattice estimates of the heavy-light baryon Λb, obtained using propagating heavy quarks. Our result is: MΛstaggeredb = 5.728 ± 0.144 ± 0.018 Gev, after extrapolation to the continuum limit and in the quenched ...
