Dramatic progress has been made over the last decade in the numerical study of quantum
chromodynamics (QCD) through the use of improved formulations of QCD on the lattice …

We have extended our program of QCD simulations with an improved Kogut-Susskind quark
action to a smaller lattice spacing, approximately 0.09 fm. Also, the simulations with a≈ 0.12 …

D s mesons are studied in three quantum channels (JP= 0+, 1+ and 2+), where experiments
have identified the very narrow D s 0*(2317), D s 1 (2460) and narrow D s 1 (2536), D s …

Radiative transitions between charmonium states offer an insight into the internal structure of
heavy-quark bound states within QCD. We compute, for the first time within lattice QCD, the …

Working with a large basis of covariant derivative-based meson interpolating fields we
demonstrate the feasibility of reliably extracting multiple excited states using a variational …

We investigate the spectroscopy and decays of the charmonium and upsilon systems in a
potential model consisting of a relativistic kinetic energy term, a linear confining term …

We present the first lattice QCD calculation with realistic sea quark content of the D+-meson
decay constant f D+. We use the MILC Collaboration's publicly available ensembles of lattice …

Results obtained by various experiments show that the D s 0*(2317) and D s 1 (2460)
mesons are very narrow states located below the DK and D* K thresholds, respectively. This …

We sum up the next-to-leading logarithmic corrections to the heavy-quarkonium hyperfine
splitting, using the nonrelativistic renormalization group. On the basis of this result, we …

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 …
