We calculate the equation of state in $2+1$ flavor QCD at finite temperature with physical strange quark mass and almost physical light quark masses using lattices with temporal extent…
Lattice QCD ensembles with four flavors of highly improved staggered quarks

- 19 December 2012
We present results from our simulations of quantum chromodynamics with four flavors of quarks: u, d, s, and c. These simulations are performed with a one-loop Symanzik improved gauge action and the…
Nonperturbative QCD Simulations with 2+1 Flavors of Improved Staggered Quarks
- A. Bazavov, C. Bernard, R. Water
- Physics
- 23 March 2009
Dramatic progress has been made over the last decade in the numerical study of quantum chromodynamics (QCD) through the use of improved formulations of QCD on the lattice (improved actions), the…
Particle–antiparticle annihilation in diffusive motion
- D. Toussaint, F. Wilczek
- Physics
- 1 March 1983
We study both numerically and analytically the time development of a system of particles and antiparticles moving diffusively and annihilating irreversibly. The asymptotic behavior is found to depend…
QCD spectrum with three quark flavors
- C. Bernard, T. Burch, D. Toussaint
- Physics
- 2 April 2001
We present results from a lattice hadron spectrum calculation using three flavors of dynamical quarks -- two light and one strange -- and quenched simulations for comparison. These simulations were…
Strange quark condensate in the nucleon in 2 + 1 flavor QCD.

The method is to evaluate quark-line disconnected correlations on the MILC lattice ensembles, which include the effects of dynamical light and strange quarks.
High-precision lattice QCD confronts experiment.

- PhysicsPhysical Review Letters
- 7 April 2003
To test the Symanzik-improved staggered-quark discretization formalism, experiment with a variety of nonperturbative calculations in QCD drawn from a restricted set of "gold-plated" quantities finds agreement to within statistical and systematic errors of 3% or less.
Results for light pseudoscalar mesons
- M. C. A. Bazavov, C. Bernard, R. Water
- Physics
- 4 December 2010
We present the current status of the MILC collaboration’s calculations of the properties of the light pseudoscalar meson sector. We use asqtad staggered ensembles with 2+1 dynamical flavors down to…
