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…
Quarkonium mass splittings in three-flavor lattice QCD
T. Burch, C. DeTar, M. Di Pierro +7
We report on calculations of the charmonium and bottomonium spectrum in lattice QCD. We use ensembles of gauge fields with three flavors of sea quarks, simulated with the asqtad im…
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…
Quarkonium mass splittings with Fermilab heavy quarks and 2+1 flavors of improved staggered sea quarks
T. Burch, C. E. DeTar, M. Di Pierro +6
We present results from an ongoing lattice study of the lowest lying charmonium and bottomonium level splittings using the Fermilab heavy quark formalism. Our objective is to test…
The CKM Matrix from Lattice QCD
Paul B. Mackenzie
Lattice QCD plays an essential role in testing and determining the parameters of the CKM theory of flavor mixing and CP violation. Very high precisions are required for lattice cal…
Visualization of semileptonic form factors from lattice QCD
C. Bernard, C. DeTar, M. Di Pierro +17
Comparisons of lattice-QCD calculations of semileptonic form factors with experimental measurements often display two sets of points, one each for lattice QCD and experiment. Here…
