Poisson Statistics in the High Temperature QCD Dirac Spectrum
Poisson Statistics the High Temperature QCD Dirac Spectrum
2011/1/6
At low temperature in the epsilon regime of QCD the low-end of the Dirac spectrum is described by random matrix theory. In contrast, there has been no similarly well established staistical description...

The phase boundary for the chiral transition in (2+1)-flavor QCD at small values of the chemical potential
the chiral transition (2+1)-flavor QCD
2011/1/6
We determine the chiral phase transition line in (2+1)-flavor QCD for small values of the light quark chemical potential. We show that for small values of the chemical potential the curvature of the p...

EOS in 2+1 flavor QCD with improved Wilson quarks by the fixed-scale approach
EOS 2+1 flavor QCD improved Wilson quarks
2011/1/6
We present the status of our study on the equation of state in 2+1 flavor QCD with non-perturbatively improved Wilson quarks coupled with the RG improved glue. We apply the T-integration method to non...

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 ($...

Evidence for a First Order, Finite Temperature Phase Transition in 8 Flavor QCD
Phase Transition 8 Flavor QCD
2011/1/6
As part of our ongoing investigations of QCD with many flavors of quarks, here we report on studies of the finite temperature phase transition for eight-flavor QCD with the DBW2 gauge action and na\"i...

Chiral Symmetry Restoration in Holographic Noncommutative QCD
Chiral Symmetry Holographic Noncommutative QCD
2010/12/23
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...
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 ...
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...
Continuum Limit Physics from 2+1 Flavor Domain Wall QCD
Continuum Limit Physics 2+1 Flavor Domain Wall QCD
2011/1/6
We present physical results obtained from simulations using 2+1 flavors of domain wall quarks and the Iwasaki gauge action at two values of the lattice spacing $a$, ($a^{-1}$=\,1.73\,(3)\,GeV and $a^{...
