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 ...

Semileptonic decays of K and D mesons in 2+1 flavor QCD
Semileptonic decays K and D mesons in 2+1 flavor QCD
2011/1/6
The experimentally measured rates of the semileptonic decays K -> pi l nu and D -> K(pi) l nu can be combined with lattice calculations of the associated form factors to precisely extract the CKM matr...

Possible splitting of deconfinement and chiral transitions in strong magnetic fields in QCD
chiral transitions strong magnetic fields in QCD
2010/12/27
We show that finite-temperature deconfinement and chiral transitions can split in a strong enough magnetic field. The splitting in critical temperatures of these transitions in a constant magnetic fie...

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...
