  The ground state and first excited state masses of Omega(b) and Omega(bb)
baryons are calculated in lattice QCD using dynamical 2+1 flavour gauge fields.
A set of baryon operators employing different combinations of smeared quark
fields was used in the framework of the variational method. Results for radial
excitation energies were confirmed by carrying out a supplementary
multiexponential fitting analysis. Comparison is made with quark model
calculations.
