Heavy baryon mass spectrum from lattice QCD with 2+1 dynamical sea quark flavors

Abstract

We investigate the mass differences of charm and bottom heavy baryons, using MILC lattice gauge configurations with 2+1 dynamical sea quark flavors. We extend our previous work to three lattice spacings: fine (a~0.09), coarse (a~0.12), and medium-coarse (a~0.15) ensembles. For extrapolations and interpolations, we apply simultaneous quadratic fits and simple linear fits with the full QCD data points for the valence quark masses as well as the sea quark masses.
