摘要：We study the heavy baryon mass spectrum on gauge configurations that include 2+1 flavors of dynamical improved staggered quarks. A valence clover heavy quark is combined with two improved staggered light quark propagators to form baryons with different flavors. We are using MILC coarse gauge configurations with a lattice spacing of about 0.12 fm. In this preliminary investigation, we explore the chiral limit by studying two light sea quark masses, three different strange valence quark masses, and nine different light valence quark masses ranging from 0.1 to 0.4 times the nominal strange quark mass.
