Charm and bottom heavy baryon mass spectrum from lattice QCD with 2+1 flavors
We present results for the mass spectrum of charm and bottom heavy baryons, using MILC coarse lattice configurations with 2+1 flavors. Clover heavy quark propagators with the Fermilab interpretation and improved staggered light quark propagators are used to construct two point functions with local operators for different flavor and spin states.
متن کاملHeavy baryon mass spectrum from lattice QCD with 2+1 flavors
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 th...
متن کاملHeavy baryon mass spectrum from lattice QCD with 2+1 dynamical sea quark flavors
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 dat...
متن کاملThe light baryon spectrum calculated with 2 + 1 flavors of domain wall fermions
Preliminary results for the light baryon spectrum computed in an on-going QCD simulation using 2+1 flavors of domain wall fermions and the Iwasaki gauge action are presented and discussed. Lattice sizes 243×64 and 323×64 with spacings 0.114 and∼ 0.08 fm are used in the calculation. The physical spatial size is thus 2.74 fm and ∼ 2.6 fm, respectively. The degenerate light quarks have masses down...
متن کاملThe spectrum of static-light baryons in twisted mass lattice QCD
We compute the static-light baryon spectrum with N f = 2 flavors of sea quarks using Wilson twisted mass lattice QCD. As light valence quarks we consider quarks, which have the same mass as the sea quarks with corresponding pion masses in the range 340MeV∼mPS ∼525MeV, as well as partially quenched quarks, which have the mass of the physical s quark. We extract masses of states with isospin I = ...
