The Ds and D+ Leptonic Decay Constants from Lattice QCD
A. Bazavov, C. Bernard, C. DeTar +16
We present the leptonic decay constants fDs and fD+ computed on the MILC collaboration's 2+1 flavor asqtad gauge ensembles. We use clover heavy quarks with the Fermilab interpretat…
The strange quark content of the nucleon in 2+1 flavor lattice QCD
Walter Freeman, Doug Toussaint
The strangeness of the nucleon, <N|ss|N> - <0|ss|0>, is a quantity of interest for interpreting the results of dark matter detection experiments as well as for exploring the struct…
Progress on charm semileptonic form factors from 2+1 flavor lattice QCD
Jon A. Bailey, A. Bazavov, C. Bernard +19
Lattice calculations of the form factors for the charm semileptonic decays D to K l nu and D to pi l nu provide inputs to direct determinations of the CKM matrix elements |V(cs)| a…
Results from the MILC collaboration's SU(3) chiral perturbation theory analysis
A. Bazavov, C. Bernard, C. DeTar +12
We present the status of the MILC collaboration's analysis of the light pseudoscalar meson sector with SU(3) chiral fits. The analysis includes data from new ensembles with smaller…
Progress on four flavor QCD with the HISQ action
MILC Collaboration, A. Bazavov, C. Bernard +11
We describe recent progress on generation of gauge configurations using the Highly Improved Staggered Quark (HISQ) action that was designed by the HPQCD/UKQCD collaboration. The HI…
SU(2) chiral fits to light pseudoscalar masses and decay constants
A. Bazavov, C. Bernard, C. DeTar +12
We present the results of fits to recent asqtad data in the light pseudoscalar sector using SU(2) partially-quenched staggered chiral perturbation theory. Superfine (a~0.06 fm) and…
