Abstract
The mass spectrum of heavy quark baryons has been computed on anisotropic lattices using quenched lattice nonrelativistic QCD. The mass splittings between spin-1/2 and spin-3/2 baryons are also calculated. Results are compared to those obtained by using a Dirac-Wilson action of the D234 type. Color hyperfine effects in heavy baryons are also discussed.
