The quark-antiquark potential and the gluonic action-density are calculated on sets of smeared gauge-field configurations at finite temperature just below the deconfinement temperature. We find the qu...

The number and the location of the monopoles observed on the lattice in QCD configurations happens to depend strongly on the choice of the gauge used to expose them, in contrast to the physical expect...

Chiral Symmetry Restoration in Holographic Noncommutative QCD
Chiral Symmetry Holographic Noncommutative QCD

We consider the noncommutative deformation of the Sakai-Sugimoto model at finite temperature and finite baryon chemical potential. The influence of the space noncommutativity on the flavor dynamics of...
Systematic errors in extracting nucleon properties from lattice QCD
Systematic errors extracting nucleon properties
2011/1/6
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 moment...

Charmonium-nucleon interaction from lattice QCD with a relativistic heavy quark action
Charmonium-nucleon lattice QCD relativistic heavy quark action
2011/1/6
Detailed information of the low-energy interaction between the charmonia ({\eta}c and J/{\psi}) and the nucleon is indispensable for exploring the formation of charmonium bound to nuclei. In order to ...

The phase-shift of isospin-2 pi-pi scattering from lattice QCD
The phase-shift of isospin-2 pi-pi scattering lattice QCD
2011/1/7
Finite-volume lattice QCD calculations offer the possibility of extracting resonance parameters from the energy-dependent elastic phase-shift computed using the Luescher technique. In this letter, as ...
We present the results of extensive simulations regarding the critical behavior at the endpoint of the Roberge-Weiss transition for N_f = 2 QCD. We confirm early evidence, presented in arXiv:0909.0254...
Possible splitting of deconfinement and chiral transitions in strong magnetic fields in QCD
Possible splitting of deconfinement chiral transitions
2011/1/7
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...
OPE, Heavy-Quark Mass, and Heavy-Meson Decay Constants from QCD Sum Rules
OPE Heavy-Quark Mass Heavy-Meson Decay Constants
2011/1/7
We present a sum-rule extraction of the decay constants of heavy-light mesons from the two-point correlator of pseudoscalar currents. To this end, we compare the perturbative expansions for the correl...
Heavy-Quark Mass and Heavy-Meson Decay Constants from QCD Sum Rules
Heavy-Quark Mass Heavy-Meson Decay Constants
2011/1/7
We present a sum-rule extraction of heavy-meson decay constants from the two-point correlator of heavy-light pseudoscalar currents. Our main concern is to control the uncertainties of the decay consta...
Electromagnetically superconducting phase of QCD vacuum induced by strong magnetic field
Electromagnetically superconducting QCD vacuum induced
2011/1/7
In this talk we discuss our recent suggestion that the QCD vacuum in a sufficiently strong magnetic field (stronger than 10^{16} Tesla) may undergo a spontaneous transition to an electromagnetically s...
