Lattice QCD at the physical point: light quark masses
Lattice QCD physical point light quark masses
2011/1/14
Ordinary matter is described by six fundamental parameters: three couplings (gravitational,
electromagnetic and strong) and three masses: the electron’s (me) and those of the up (mu)
and down (md) q...
Nucleon strange quark content from two-flavor lattice QCD with exact chiral symmetry
Nucleon strange quark content two-flavor lattice QCD exact chiral symmetry
2011/1/13
Strange quark content of the nucleon hN|¯ss|Ni is calculated in dynamical lattice QCD employing the overlap fermion formulation. For this quantity, exact chiral symmetry guaranteed by the Ginspar...

Exploring quark transverse momentum distributions lattice QCD
2011/1/13
We discuss in detail a method to study transverse momentum dependent parton distribution
functions (TMDs) using lattice QCD. To develop the formalism and to obtain rst numerical results,we directly ...
Flavor structure of the baryon-baryon interaction from lattice QCD

2011/1/13
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...
Systematic errors in extracting nucleon properties from lattice QCD
Systematic errors extracting nucleon properties lattice QCD
2011/1/13
Form factors of the nucleon have been extracted from experiment with high precision. However,
lattice calculations have failed so far to reproduce the observed dependence of form factors on
the mome...
Analysis of the $N_f=2+1$ lattice QCD results on the lowest-lying baryon masses using covariant ChPT

We perform a non-perturbative lattice calculation of the P-wave pion-pion scattering phase in
the -meson decay channel using two flavors of maximally twisted mass fermions at pion masses
