Simulations with dynamical HISQ quarks

A. Bazavov, C. Bernard, C. DeTar +11

We report on the status of a program of generating and using configurations with four flavors of dynamical quarks, using the HISQ action. We study the lattice spacing dependence of…

Results for light pseudoscalar mesons

MILC Collaboration, A. Bazavov, C. Bernard +13

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 dynamica…

Scaling studies of QCD with the dynamical HISQ action

MILC collaboration, A. Bazavov, C. Bernard +12

We study the lattice spacing dependence, or scaling, of physical quantities using the highly improved staggered quark (HISQ) action introduced by the HPQCD/UKQCD collaboration, com…

Multi-hadron states in Lattice QCD spectroscopy

J. Foley, J. Bulava, K. J. Juge +3

The ability to reliably measure the energy of an excited hadron in Lattice QCD simulations hinges on the accurate determination of all lower-lying energies in the same symmetry cha…

Topological susceptibility with the asqtad action

MILC collaboration, A. Bazavov, C. Bernard +12

Chiral perturbation theory predicts that in quantum chromodynamics (QCD), light dynamical quarks suppress the gauge-field topological susceptibility of the vacuum. The degree of su…

QCD thermodynamics with nonzero chemical potential at and effects from heavy quarks

C. DeTar, L. Levkova, Steven Gottlieb +4

We extend our work on QCD thermodynamics with 2+1 quark flavors at nonzero chemical potential to finer lattices with . We study the equation of state and other thermodynamic…

Tuning Fermilab Heavy Quarks in 2+1 Flavor Lattice QCD with Application to Hyperfine Splittings

C. Bernard, C. DeTar, M. Di Pierro +15

We report the non-perturbative tuning of parameters--- kappa_c, kappa_b, and kappa_crit ---that determine the heavy-quark mass in the Fermilab action. This requires the computation…

The excited hadron spectrum in lattice QCD using a new method of estimating quark propagation

C. Morningstar, A. Bell, J. Bulava +7

Progress in determining the spectrum of excited baryons and mesons in lattice QCD is described. Large sets of carefully-designed hadron operators have been studied and their effect…
