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…
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…
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…
Neutral B-meson mixing from unquenched lattice QCD with domain-wall light quarks and static b-quarks
Conrado Albertus, Yasumichi Aoki, Peter A. Boyle +11
We demonstrate a method for calculating the neutral B-meson decay constants and mixing matrix elements in unquenched lattice QCD with domain-wall light quarks and static b-quarks.…
