The $Δ(1232)$ axial charge and form factors from lattice QCD
The $Δ(1232)$ axial charge factors lattice QCD
2011/7/21
We present the first calculation on the $\Delta$ axial-vector and pseudoscalar form factors using lattice QCD. Two Goldberger-Treiman relations are derived and examined.
Extraction of Hadron Interactions above Inelastic Threshold in Lattice QCD
nuclear potential hadron interaction lattice QCD
2011/7/21
We propose a new method to extract hadron interactions above inelastic threshold from the Nambu-Bethe-Salpter amplitude in lattice QCD.
Three-nucleon forces (3NF) are investigated from two-flavor lattice QCD simulations. We utilize the Nambu-Bethe-Salpeter (NBS) wave function to determine two-nucleon forces (2NF) and 3NF in the same f...
The complex patterns of the hadronic spectrum have puzzled physicists since the early discovery of the "particle zoo" in the 1960s. Today, the properties of these myriad particles are understood to be...

2011/7/21
Lattice simulations of QCD have produced precise estimates for the masses of the lowest-lying hadrons which show excellent agreement with experiment.
Equation of state at finite baryon density based on lattice QCD
lattice QCD baryon density Equation of state
2011/7/21
We employ the lattice QCD data on Taylor expansion coefficients to extend our previous parametrization of the equation of state to finite baryon density.

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 ...

Ordinary matter is described by six fundamental parameters: three couplings (gravitational, electromagnetic and strong) and three masses: the electron's ($m_e$) and those of the up ($m_u$) and down ($...
