Analysis of the $N_f=2+1$ lattice QCD results on the lowest-lying baryon masses using covariant ChPT
the $N_f=2+1$ lattice QCD results lowest-lying baryon masses
2011/1/6
We review recent progress in the understanding of low-energy baryon structure by means of chiral perturbation theory. In particular, we discuss the application of this formalism to the description of ...

Lattice QCD at the physical point: Simulation and analysis details
Lattice QCD the physical point
2011/1/6
We give details of our precise determination of the light quark masses m_{ud}=(m_u+m_d)/2 and m_s in 2+1 flavor QCD, with simulated pion masses down to 120 MeV, at five lattice spacings, and in large ...

Flavor structure of the baryon-baryon interaction from lattice QCD
baryon-baryon interaction lattice QCD
2011/1/6
We investigate baryon-baryon (BB) interactions in the 3-flavor full QCD simulations with degenerate quark masses for all flavors. The BB potentials in the orbital S-wave are extracted from the Nambu-B...

Instantaneous interquark potential in generalized Landau gauge in SU(3) lattice QCD: a possible gauge for the quark potential model
Instantaneous interquark potential SU(3) lattice QCD
