High-Precision Charm-Quark Mass from Current-Current Correlators in Lattice and Continuum QCD
- I. Allison, E. Dalgic, +12 authors C. Sturm
- Physics
- 20 May 2008
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-vector… Expand
High-Precision c and b Masses, and QCD Coupling from Current-Current Correlators in Lattice and Continuum QCD
- C. McNeile, C. Davies, E. Follana, K. Hornbostel, G. Lepage
- Physics
- 1 September 2008
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.
- C. Davies, C. McNeile, +6 authors H. Trottier
- Physics, Medicine
- Physical review letters
- 16 October 2009
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 obtain… Expand
Light hadrons from lattice QCD with light (u, d), strange and charm dynamical quarks
- R. Baron, P. Boucaud, +17 authors E. collaboration
- Physics
- 29 April 2010
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
- B. Chakraborty, C. Davies, +6 authors C. McNeile
- Physics
- 18 August 2014
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
- R. Dowdall, C. Davies, G. Lepage, C. McNeile
- Physics
- 7 March 2013
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/d… Expand
Decay width of light quark hybrid meson from the lattice
- C. McNeile, C. Michael
- Physics
- 6 March 2006
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 amplitudes… Expand
Towards the glueball spectrum from unquenched lattice QCD
- E. Gregory, A. Irving, +4 authors E. Rinaldi
- Physics
- 9 August 2012
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 glueball… Expand
Exotic mesons in quenched lattice QCD
- M. C. Bernard, T. DeGrand, +8 authors M. Wingate
- Physics
- 11 July 1997
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 hybrids… Expand
Semileptonic $B_c$ decays from full lattice QCD
- A. Lytle, B. Colquhoun, C. Davies, J. Koponen, C. McNeile
- Physics
- 18 May 2016
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 QCD… Expand
