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…
Taste symmetry and QCD thermodynamics with improved staggered fermions
Alexei Bazavov, Peter Petreczky
Taste symmetry violations in staggered fermion formulations correlate strongly with the cut-off (lattice spacing) dependence in thermodynamic quantities. Better taste symmetry on t…
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…
Semileptonic decays of K and D mesons in 2+1 flavor QCD
Jon A. Bailey, A. Bazavov, C. Bernard +17
The experimentally measured rates of the semileptonic decays K -> pi l nu and D -> K(pi) l nu can be combined with lattice calculations of the associated form factors to precisely…
B -> D* l nu at zero recoil: an update
Jon A. Bailey, A. Bazavov, C. Bernard +17
We present an update of our calculation of the form factor for B -> D* l nu at zero recoil, with higher statistics and finer lattices. As before, we use the Fermilab action for b a…
Staggered chiral perturbation theory in the two-flavor case and SU(2) analysis of the MILC data
A. Bazavov, C. Bernard, C. DeTar +11
In the light pseudoscalar sector, we study rooted staggered chiral perturbation theory in the two-flavor case. The pion mass and decay constant are calculated through NLO for a par…
