High-Precision Charm-Quark Mass from Current-Current Correlators in Lattice and Continuum QCD
We use lattice QCD simulations, with MILC configurations and HISQ $c$-quark propagators, to make very precise determinations of moments of charm-quark pseudoscalar, vector and axial-vectorExpand

High-Precision c and b Masses, and QCD Coupling from Current-Current Correlators in Lattice and Continuum QCD
We extend our earlier lattice-QCD analysis of heavy-quark correlators to smaller lattice spacings and larger masses to obtain new values for the c mass and QCD coupling, and, for the first time,Expand

Precise charm to strange mass ratio and light quark masses from full lattice QCD.
By using a single formalism to handle charm, strange, and light valence quarks in full lattice QCD for the first time, we are able to determine ratios of quark masses to 1%. For m(c)/m(s) we obtainExpand

Light hadrons from lattice QCD with light (u, d), strange and charm dynamical quarks
We present results of lattice QCD simulations with mass-degenerate up and down and mass-split strange and charm (Nf = 2 + 1 + 1) dynamical quarks using Wilson twisted mass fermions at maximal twist.Expand

High-precision quark masses and QCD coupling from $n_f=4$ lattice QCD
We present a new lattice QCD analysis of heavy-quark pseudoscalar-pseudoscalar correlators, using gluon configurations from the MILC Collaboration that include vacuum polarization from u , d , s ,Expand

Vus from pi and K decay constants in full lattice QCD with physical u, d, s and c quarks
We determine the decay constants of the π and K mesons on gluon field configurations from the MILC Collaboration including u , d , s , and c quarks. We use three values of the lattice spacing and u/dExpand

Decay width of light quark hybrid meson from the lattice
Lattice QCD with N{sub f}=2 flavours of sea quark is used to explore the spectrum and decay of a J{sup PC}=1{sup -+} spin-exotic hybrid meson. We test lattice determination of S-wave decay amplitudesExpand

Towards the glueball spectrum from unquenched lattice QCD
A bstractWe use a variational technique to study heavy glueballs on gauge configurations generated with 2+1 flavours of ASQTAD improved staggered fermions. The variational technique includes glueballExpand

Exotic mesons in quenched lattice QCD
Since gluons in QCD are interacting fundamental constituents just as quarks are, we expect that in addition to mesons made from a quark and an antiquark, there should also be glueballs and hybridsExpand

Semileptonic $B_c$ decays from full lattice QCD
We present first lattice QCD results for semileptonic form factors for the decays $B_c \to \eta_c l \nu$ and $B_c \to J/\psi l \nu$ over the full $q^2$ range, using both improved non-relativistic QCDExpand
