Spectroscopy of triply-charmed baryons from lattice QCD    [PDF]

M. Padmanath, Robert G. Edwards, Nilmani Mathur, Michael Peardon
The spectrum of excitations of triply-charmed baryons is computed using lattice QCD including dynamical light quark fields. The spectrum obtained has baryonic states with well-defined total spin up to 7/2 and the low-lying states closely resemble the expectation from models with an SU(6)x O(3) symmetry. Energy splittings between extracted states, including those due to spin-orbit coupling in the heavy quark limit are computed and compared against data at other quark masses.
